# Mean Girls

Mean Girls is a 2004 American teen comedy film directed by Mark Waters and written by Tina Fey. It stars Lindsay Lohan, Rachel McAdams, Tim Meadows, Ana Gasteyer, Amy Poehler, and Fey. The film follows Cady Heron (Lohan), a naïve teenager who transfers to an American high school after years of homeschooling in Africa. Cady quickly befriends two outcasts (Lizzy Caplan and Daniel Franzese), with the trio forming a plan to exact revenge on Regina George (McAdams), the leader of an envied clique known as the Plastics.
Fey conceived the idea for Mean Girls after reading the self-help book Queen Bees and Wannabes. The book describes female high school social cliques, school bullying, and the resulting damaging effect on teenagers. Fey also drew from her own experience at Upper Darby High School, in Upper Darby Township, Pennsylvania, as an inspiration for some of the film's concepts. Saturday Night Live creator Lorne Michaels served as a producer; Fey was a long-term cast member and writer for Saturday Night Live. Principal photography took place from September to November 2003. Although set in the Chicago suburb of Evanston, Illinois, filming took place primarily in Toronto, Canada.
Mean Girls premiered at the Cinerama Dome in Los Angeles on April 19, 2004, and was theatrically released in the United States on April 30, by Paramount Pictures. The film grossed over $130 million worldwide and received generally positive reviews from critics, who praised Waters's direction, Fey's screenplay, its humor, and the performances; especially lauded was Lohan's acting, which earned several accolades, including three Teen Choice Awards and two MTV Movie Awards, and in 2021, was listed as the eleventh-best performance of the 21st century by The New Yorker.
A made-for-television sequel, Mean Girls 2, premiered on ABC Family in January 2011. Mean Girls also spawned various adaptations, including a stage musical, which premiered on Broadway in March 2018, with a film adaptation released in January 2024.

## Plot

After being homeschooled for her entire life and having spent the last twelve years in Africa, 16-year-old Cady Heron begins her first day at North Shore High School. She has trouble making friends and is put down by the teachers on her first day, although she does befriend outcasts Janis Ian and Damian Leigh. The next day, Janis and Damian explain the school's various cliques to her, warning her about the "Plastics", a trio of pretty and wealthy but mean girls consisting of the ruthless queen bee Regina George, the insecure gossiper Gretchen Wieners, and the sweet but dimwitted Karen Smith. However, Regina, Gretchen, and Karen take a shine to Cady and unexpectedly invite her to join the Plastics. Upon realizing this, Janis hatches a plan to get revenge on Regina, whom she accuses of "ruining her life", and ruin her life in turn. Later that day, Cady becomes infatuated with her classmate Aaron Samuels, to which Karen and Gretchen warn her that, as Regina's ex-boyfriend, he is off-limits.
Regina discovers Cady's infatuation with Aaron and tells Cady she does not care about their relationship and is cool with it. Despite Janis's insistence that Regina is "evil", Cady comes to enjoy hanging out with the group at the mall and at Regina's mansion as well as writing insulting remarks about their classmates and teachers in a diary called the "Burn Book", leaving her on the fence about Janis' plan. However, at a Halloween house party, instead of talking to Aaron on Cady's behalf, Regina kisses him in front of her and resumes their relationship. Feeling betrayed, an enraged Cady fully commits to the plan.
Over the following months, Cady, with Janis and Damian's help, manages to trick Gretchen into revealing her secrets, break up Regina's relationship with Aaron (and spend time with him by pretending to need math tutoring), and cause her to gain weight by giving her high-calorie snack bars under the pretense that they are diet food. After violating the Plastics' dress code rules by wearing sweatpants, the only thing that fit her, on Monday, Regina is kicked out of the group and Cady becomes the new "queen bee".
With her parents out of town, Cady throws a house party. She drunkenly admits to Aaron that she does not actually need math tutoring, to which he renounces her as being no better than Regina. Janis and Damian angrily confront Cady for throwing a party instead of attending the former's art show and declare that she has become as plastic as she pretended to be. Meanwhile, Regina is enraged to discover Cady's sabotage and plans to distribute photocopies of the Burn Book to frame Cady, and by extension Gretchen and Karen. Regina also inserts fake slander of herself in the book in order to avoid suspicion and thus focus blame on the other 3 Plastics.
Regina spreads the contents of the book throughout the hallways, inciting chaos. Principal Duvall and math teacher Ms. Norbury gather the female junior students in the gym to talk through their social issues. During this, Janis reveals her plan against Regina to the latter's face and openly mocks her, much to the students' excitement. Regina furiously storms out, pursued by an apologetic Cady. Regina then goes on a massive rant against Cady that is cut off by a school bus plowing into her, fracturing her spine. Rumors circulate that Cady intentionally pushed Regina in front of the bus.
After realizing a comment she wrote in the Burn Book has framed Ms. Norbury as a drug dealer, Cady decides to take full responsibility for the book, clearing Regina, Gretchen, and Karen of any punishment but also becoming a social pariah in the process. To earn extra credit, Cady joins the school Mathletes, moderated by Ms. Norbury and led by fellow student Kevin Gnapoor, at the state finals, answering the tiebreaker correctly to win the championship. The team arrives at the Spring Fling dance, where Cady is unexpectedly elected queen. She breaks the plastic tiara and distributes the pieces to others in the crowd, makes peace with Janis, Damian, and the Plastics, and shares a slow dance and a kiss with Aaron.
The Plastics disband by the time senior year begins, as a fully-recovered Regina joins the school's lacrosse team to channel her anger positively, Gretchen joins the "Cool Asian" clique and becomes their biggest follower and Karen becomes the school weather girl while Cady begins dating Aaron as well as continuing to hang out with Janis, who starts dating Kevin, and Damian. While reflecting to herself on the relative social peace that has taken over North Shore High, Cady notices a trio of new "Junior Plastics" and wonders how long they will last, as she jokingly imagines them being hit by a school bus.

## Production
### Development

Tina Fey read Rosalind Wiseman's Queen Bees and Wannabes and called Saturday Night Live producer Lorne Michaels to suggest it could be turned into a film. Michaels contacted Paramount Pictures, who purchased the rights to the book. As the book is nonfiction, Fey wrote the plot from scratch, borrowing elements from her own experience at Upper Darby High School and her impressions of Evanston Township High School and New Trier Township High School from her time living in the Chicago area, upon which the film's fictional "North Shore High School" is based.
Fey named many characters after real-life friends. In a 2014 interview about the movie, she told Entertainment Weekly, "I tried to use real names in writing because it's just easier." Main character Cady Heron was named after Fey's college roommate Cady Garey. Damian was named after Fey's high school friend Damian Holbrook, who went on to become a writer for TV Guide. Minor character Glenn Coco is named after a friend of Fey's older brother; the real Glenn Coco works as a film editor in Los Angeles. Janis Ian was named after singer Janis Ian, who was one of the two musical guests on the first Saturday Night Live episode, in which she sang her hit song "At Seventeen", which can be heard playing in the background when the girls are fighting at Regina's house. The film was originally going to be called "Homeschooled".

### Casting

Fey, Michaels, and Paramount Pictures chairman Sherry Lansing wanted to cast Lindsay Lohan in the film after seeing her performance in Freaky Friday (2003). Lohan was originally set to play Regina George, but the casting team ended up feeling she was their strongest choice for the role of Cady Heron, and since executives feared the "mean girl" role would alienate her audience, she eventually agreed to play the lead. Rachel McAdams was cast as Regina because Fey felt McAdams being "kind and polite" made her perfect for such an evil-spirited character and director Mark Waters, who previously directed Lohan in Freaky Friday, felt Lohan was "a little intimidated" by her which made him like their dynamic. McAdams had originally auditioned for the role of Cady but was deemed "a bit too old" for the character. Kristen Stewart, Michelle Trachtenberg and Mae Whitman were considered for the role of Cady opposite Lohan's Regina George early on. According to casting director Marci Liroff, Blake Lively was the top choice to play the role of Karen Smith, but was told by the producers to keep looking. Amanda Seyfried originally auditioned for Regina, and although Waters thought she was "fantastic", the producers instead suggested her for Karen due to her "spacey and daffy sense of humor". Leighton Meester, Haylie Duff, Kate Mara and Megan Fox were also up for the role of Karen. America Ferrera and Kat Dennings were both heavily favored for the role of Janis Ian. Lizzy Caplan was at first considered too beautiful for that role, for which Waters felt a "Kelly Osbourne-type" was necessary, but Caplan was chosen for being able to portray raw emotion. Evan Rachel Wood was offered a role in the film, but turned it down due to scheduling conflicts, a decision she later regretted. Mary Elizabeth Winstead was asked to audition for the role of Gretchen Wieners, but her mother declined as she disliked the script. Ashley Tisdale and Vanessa Hudgens also auditioned for Gretchen. Jonathan Bennett was a last-minute replacement after the actor originally slated to play the role of Aaron Samuels was fired. James Franco had previously been considered for Aaron, and Penn Badgley, Jared Padalecki and Max Minghella all auditioned as well. Fey's decision to hire Bennett was due to his resemblance to her longtime SNL co-star Jimmy Fallon. Lacey Chabert and Daniel Franzese were the last actors tested for their roles. Fey wrote two roles based on fellow SNL alumni Tim Meadows and Amy Poehler, the latter of whom Fey thought the producers would perceive as too young to portray a teenager's mother. The cast additionally ended up with a fourth veteran of the show, Ana Gasteyer.

### Filming

Although set in Evanston, Illinois, the film was mostly shot in Toronto, Ontario, at Etobicoke Collegiate Institute and Malvern Collegiate Institute, as well as at Montclair High School in Montclair, New Jersey. Landmarks include the University of Toronto's Convocation Hall and Sherway Gardens. Principal photography commenced on September 27, and concluded on November 25, 2003.

## Soundtrack

Mean Girls: Music from the Motion Picture was released by Rykodisc and Bulletproof Records on September 21, 2004, the same day as the DVD release. The album featured songs performed by the Donnas, Pink, Kelis, Samantha Ronson, Boomkat, Blondie, Katy Rose and Peaches amongst several others.

## Home media

Mean Girls was released on VHS and DVD in North America on September 21, 2004, five months after its theatrical release. It was released in a special collector's edition, in both its original 1.77:1 widescreen aspect ratio and a 1.33:1 fullscreen crop, including several deleted scenes, a blooper reel, three TV spots, the theatrical trailer, previews, and three featurettes. A Blu-ray version of the film was released on April 14, 2009. The film was later re-released on a 15th-anniversary Blu-ray in 2019. A limited SteelBook edition of the film was released in September 2022. It was released on 4K Ultra HD Blu-ray for the first time on April 30, 2024, in commemoration of the film's 20th anniversary along with the release of the 2024 film.

## Reception
### Box-office

In its opening weekend, Mean Girls grossed $24.4 million from 3,159 screens at 2,839 theaters in the United States, ranking number one at the box office and averaging $8,606 per venue. The film closed on September 9, 2004, grossing $86.1 million domestically and $44.4 million internationally for a total worldwide gross of $130.5 million. Paramount said the audience was 75% female, and 50% was under the age of 18. Over 90% of moviegoers rated the picture either "excellent" or "very good", and positive notices remained strong even outside the target demographic; ratings were over 80% positive from men in their thirties.

### Critical response

Mean Girls received largely positive reviews; critics lauded Lohan's and McAdams's performances and labeled the film as Seyfried and Caplan's breakthrough roles. Review aggregation website Rotten Tomatoes gives the film an approval rating of 84% based on 219 reviews, with an average rating of 6.90/10. The site's critical consensus states: "Elevated by a brilliant screenplay and outstanding ensemble cast, Mean Girls finds fresh, female-fronted humor in the high school experience." On Metacritic, the film has a score of 66 out of 100, based on 39 critics, indicating "generally favorable reviews". Audiences polled by CinemaScore, gave the film an average grade of "A−" on an A+ to F scale.
Roger Ebert of the Chicago Sun-Times gave the film three stars out of four, writing: "In a wasteland of dumb movies about teenagers, Mean Girls is a smart and funny one." Ann Hornaday of The Washington Post wrote that it "boasts a one-two-three punch in star Lindsay Lohan, screenwriter Tina Fey and director Mark Waters, and, indeed, it delivers a knockout". The screenplay was highly praised by critics with Peter Travers of Rolling Stone calling it "comic gold". In April 2004, Mick LaSalle of the San Francisco Chronicle wrote, "as in The House of Yes and Freaky Friday, Waters keeps it wild but real", noting that "all the supporting performances go right to the edge of absurdity without crossing the line into random zaniness." Entertainment Weekly put it on its end-of-the-decade "best-of" list, saying: "'Fetch' may never happen, but 2004's eminently quotable movie is still one of the sharpest high school satires ever. Which is pretty grool, if you ask me!" In 2006, Entertainment Weekly had also named it the 12th-best high school film of all time: "While Mean Girls is technically a comedy, its depiction of girl-on-girl cattiness stings incredibly true." In 2012, Rotten Tomatoes included the film in its "Top 50 Greatest Teen Comedies" list. In 2021, Marie Claire ranked Mean Girls as the best 2000s movie, calling it "the '00s pop culture staple".
In 2020, Hornaday included Mean Girls at No. 8 in her list "The 34 Best Political Movies Ever Made". She wrote: "[I]n addition to the usual adolescent high jinks and catty comebacks, screenwriter Tina Fey managed to create an incredibly insightful taxonomy of hierarchical power as it is amassed, wielded and ultimately dismantled — all within the complicated context of high school politics, Queen Bee-enforced gender norms and internalized sexism. That's a lot to accomplish, even if we never exactly made 'fetch' happen".
In March 2021, Richard Brody of The New Yorker ranked Lohan's performance as the eleventh best of the 21st century up to that point, praising her "blend of charisma and awkwardness, innocence and guile" as well as "faux-casual earnestness" she used for dialogue. In 2022, Rolling Stone ranked Mean Girls as the twentieth greatest comedy of the 21st century, saying: "Tina Fey established herself as one of America's best comedy writers courtesy of this instant teen-movie classic, which boasts one of the most quotable scripts of the past 20 years", while IndieWire ranked it as the fifteenth best comedy of the 21st century, calling the script "effortlessly funny, but what makes the film truly timeless has more to do with the actors' ability to find the human grace notes amid the absurd high school hijinks (Kälteen Bars, anyone?) and instant-classic one-liners ("That's so fetch"). It's a high school comedy with broad genre humor and specific insight into teenage anxieties, and for that, it stands the test of time." In October 2022, The Independent also included Lohan's role in a list of "outstanding performances", stating that she "gives a pretty flawless performance, dexterously balancing the film's irreverent comic tone with moments of occasional pathos."

## Cultural impact

Mean Girls has become a pop culture phenomenon. Fans have made GIFs and memes of the film and posted them on various social media platforms, including Facebook, Twitter and Tumblr. It is considered one of the most quotable films of all time. In an interview about the film, Fey noted: "Adults find it funny. They are the ones who are laughing. Young people watch it like a reality show. It's much too close to their real experiences so they are not exactly guffawing." October 3 began being dubbed "Mean Girls Day" on social media especially in 2012, alluding to a line by Cady, the protagonist. People also celebrate by wearing pink based on a line by Karen, another character. Clothing designers have printed quotes and other iconic imagery onto clothing and various merchandise.
The cast have reunited in video over the years on that day for various causes. In 2017, a GoFundMe was created to raise money for the victims of the Las Vegas shooting and the National Compassion Fund. In 2019, they collaborated with the Thirst Project to fund a freshwater well in Uganda. In 2020, the cast was honored with the Pioneering Spirit Award for their #MeanGirlsDoGood campaign. On October 3, 2020, Katie Couric moderated a virtual cast reunion to reminisce about the film. Organized in collaboration with HeadCount to promote voting in the 2020 United States presidential election, it was the first time the entire cast gathered since the 2004 premiere. Paramount Pictures released the entire film for free streaming on TikTok in 23 snippets to celebrate Mean Girls Day 2023. The hashtag "#meangirlsday" was one of the top trends on the platform that month.
American singer-songwriter Mariah Carey has said several times that she is a fan, quoting the film in numerous interviews and TV appearances, including a 2013 episode of American Idol. Carey's 2009 single, "Obsessed", begins with an interlude quote where she says, "And I was like, 'Why are you so obsessed with me?'", a line from Regina. Carey's ex-husband, Nick Cannon, revealed that the song was inspired by the film. In September 2020, Fey quizzed Carey to prove how much of a "superfan" she is on Billboard's Quizzed video series. Meanwhile, British band Wet Leg quotes the film ("Is your muffin buttered?/Would you like us to assign someone to butter your muffin?") in their 2021 song "Chaise Longue".
In August 2013, the White House tweeted a photo of President Obama's dog, Bo, holding a tennis ball and captioning: "Bo, stop trying to make fetch happen". Taco Bell made a reply to the White House, also using one of the quotes from the film. In June 2018, the official Twitter account of the Israeli Embassy in the U.S. made headlines when it responded to a tweet by Iranian leader Ali Khamenei, calling Israel "a malignant cancerous tumor", with an animated GIF of the "Why are you so obsessed with me?" quote. In March 2019, Hillary Clinton tweeted a GIF of the same quote which went viral for being considered a response to Donald Trump. At the 2013 People's Choice Awards, Jennifer Lawrence referenced the film in her speech when she won Favorite Movie Actress.
Multiple scenes have been reenacted and parodied by various celebrities throughout the years following its release, including Ed Sheeran, Iggy Azalea, Amber Rose and Waka Flocka Flame during a 2014 skit for MTV. In 2013, a Tumblr called "Les Mean Girls" emerged, which coupled lines from the film with images from the 2012 film adaptation of the musical Les Misérables. The scene where Janis explains to Cady the cliques of their school is parodied in the 2008 superhero/teen spoof Superhero Movie, where Trey points out the different groups of cliques to Rick Riker. One of the cliques is "Frodos" – kids dressed up as Hobbits akin to Frodo, The Lord of the Rings character, and another the "Scarface Society" – dressed up as Al Pacino's character Tony Montana from the 1983 film Scarface.
In June 2020, Irish Taoiseach Leo Varadkar referenced the film during a COVID-19 lockdown news briefing. Varadkar stated that "some have asked whether there is a limit to what we can achieve", before drawing upon a line from the film: "My answer is that the limit does not exist." Lord of the Rings and The Goonies actor Sean Astin bet the Irish leader "50 quid" to quote Mean Girls in his next speech.
The sixth episode of the third season of How to Get Away with Murder included several references to the film, including Michaela Pratt using the line "you can't sit with us", Annalise Keating eating her lunch in a toilet cubicle after feeling like an outcast, Laurel Castillo wearing sweatpants on a Monday, and Simon Drake calling several other students "mean girls". In June 2021, actress Aimee Lou Wood mentioned the scene where Cady broke her Spring Fling crown in pieces and shared it with girls around her. She said: "Now, I said that I'd break [this award] into pieces and share it with everyone, It's solid, Daisy [Haggard], It's solid! So I'll give you a metaphorical piece to everyone in my category, especially Emma Mackey who's the best scene partner and best friend..." The second novel by American author Karen M. McManus, Two Can Keep a Secret, includes a reference to a line in the film, where the character Ezra refers to his school's prom committee as looking like "they wear pink on Wednesdays".
In October 2024, the film was released in North American theaters again by Fathom Events for its 20th anniversary.
To celebrate the film's 20th anniversary, Paramount collaborated with MGA Entertainment to feature Cady and the Plastics as limited-edition Bratz dolls. The collaboration collection will release each character on separate dates throughout October 2024, with Cady on the 3rd, Regina on the 17th and Karen and Gretchen on the 31st (Halloween).

## Legacy
### Works inspired by Mean Girls

In early 2014, Warner Bros. Pictures and New Line Cinema announced a planned release date of May 8, 2015, for a film adapted from another book penned by Rosalind Wiseman. The project was titled Mean Moms, despite not being announced as a spin-off of Mean Girls. Beth McCarthy-Miller was set to direct with Jennifer Aniston to star. However, in May 2014, New Line Cinema pulled the film from its proposed release date of May 2015.
In 2018, Jonathan Bennett, who portrayed Aaron Samuels, released a cookbook inspired by the film, called "The Burn Cookbook: Real Recipes to Feed Your Inner Plastic." The following year, he teamed up with Nocking Point Wines to release a limited rosé wine edition.
Ariana Grande parodied the film in the music video for her 2018 song "Thank U, Next". Actors Bennett and Stefanie Drummond appeared in the video. A clip from the film was featured in a 2020 Discover Card commercial, which aired during the Super Bowl LIV. K-pop singer Sunmi named her song "You Can't Sit with Us", after a quote from the film.
A Mean Girls-themed pop-up restaurant in Santa Monica called "Fetch" was announced in 2020 as well. Primark launched a loungewear range inspired by the film in October 2019. On October 3, 2020, the Young Veterans Brewing Company released a Mean Girls-themed beer called "Army Pants & Flip Flops". Several Mean Girls-themed events, merchandising products and screenings have been often organized and produced in homage to the film.
In August 2020, Screen Junkies released an Honest Trailers episode, calling the film "the best thing to come out of that era," with Screen Rant's Daniel Gillespie saying: "Mean Girls remains entertaining, funny, and, most importantly, accurate. [...] That relevance almost two decades later proves that Mean Girls is deserving of its classic status," and Slashfilm's Ethan Anderton writing that the "generation-defining high school movie" not only captures the teenage culture of the early 2000s perfectly, "but it's also hilariously clever for being adapted from a non-fiction parenting advice book [...] Mean Girls is great because it captures that cruel teen vibe perfectly, and it tries to deliver a nice wholesome message to fight it, which kids will laugh at, agree with, and then never do anything about." In September 2020, the Pillsbury Company released a limited edition of Toaster Strudel featuring pink icing and Mean Girls packaging to pay homage to its movie-claimed inventor's daughter, Gretchen Wieners. In October 2023, Nestlé's Coffee Mate announced that a limited-edition pink frosting flavored creamer would be available from January 2024 to celebrate the film's 20th anniversary.
In November 2023, Walmart unveiled its annual holiday campaign featuring much of the original cast, including Lohan, Seyfried, Chabert, Franzese, and Surendra, reprising their roles as adults and recreating the film's scenes with modern twists.

In 2010, a Mean Girls video game developed by Crush Digital Media and planned to be published by 505 Games for the Nintendo DS handheld game console was announced, but was ultimately canceled before release. Nearly completed before cancellation, the game resurfaced in 2021 by YouTuber Ray Mona (also known as Raven Simone), who received a file for the game from an anonymous email. A full playthrough was uploaded to her channel on July 15, 2021.
In 2015, Episode launched an interactive animated web story entitled Senior Year. It picks up after the events of the film with the player taking the role of a new student who enters North Shore during senior year. It was followed by two other stories, Sorority Rush and Spring Break.

#### Musical

On January 28, 2013, Fey confirmed that a stage musical adaptation was in the works. Fey wrote the book of the show, while her husband, Jeff Richmond, composed the music with lyrics by Nell Benjamin. Directed by Casey Nicholaw, the original production premiered at the National Theatre in Washington, D.C., on October 31, 2017, for pre-Broadway tryouts. The show transferred to Broadway at the August Wilson Theatre, with previews beginning on March 12, 2018, and official opening on April 8, 2018.
The original cast featured Erika Henningsen as Cady, Taylor Louderman as Regina, Barrett Wilbert Weed as Janis, Grey Henson as Damian, Ashley Park as Gretchen, and Kate Rockwell as Karen. The show received positive reviews from critics, and was nominated for twelve awards at the 72nd Tony Awards, including Best Musical. An original Broadway cast recording was released on May 18, 2018. Due to the COVID-19 pandemic, the show played its final performance on Broadway on March 11, 2020, after one performance with a mostly new cast.
On January 23, 2020, Fey announced that a film adaptation of the stage musical was in active development.

Richmond and Benjamin also returned to rework their songs from the musical.
The musical film was released theatrically on January 12, 2024, by Paramount Pictures, after being originally set to premiere on the streaming service Paramount+.

Ashley Park, who originated the role of Gretchen in the stage musical, makes a cameo in the film. It received mixed reviews from critics, and proved successful at the box office, although not to the same degree as the original.

#### Novels

A novelization based on the script, by author Micol Ostow, was released in September 2017 by Scholastic. Another novelization – written in the style of William Shakespeare – by Ian Doescher was released in April 2019, under the title William Shakespeare's Much Ado About Mean Girls.

Meadows is the only original cast member to return in the sequel.

### Potential sequel

In late September 2014, discussions arose that Lohan had pitched an idea to Fey for a sequel. Later that year, Lohan, along with other cast members of the original film, asked Fey to write a screenplay for it. The idea was brought up during a 10th anniversary of the film in Entertainment Weekly, with Fey declaring she regretted not doing a sequel closer to its original release: "At the time we did want to start the conversation about the sequel, and for whatever reason I was like, 'No!!! We shouldn't do that!' Now I look back and I'm like, 'Why?' But now, no—it's too late now." Seyfried had previously said she was "really willing to pursue" a sequel and was unsure why it had not happened. In December 2016, Lohan mentioned she was still trying to pitch a sequel, with the hopes of Jamie Lee Curtis and Jimmy Fallon appearing in the film. She said she knew Fey, Michaels and Paramount were busy, declaring: "I will keep forcing it and pushing it on them until we do it." In October 2018, Seyfried said people needed to start a campaign for it to finally come into fruition. In January 2019, Lohan was interviewed by Howard Stern who wondered whether the sequel would ever happen. Lohan repeated her interest in revisiting the role and confirmed she had spoken to Fey about it, also saying sequel plans were not currently in the works, "I think they can't do it right now. I've spoken to her [Tina], but it can't happen without her and all of the cast. [...] Sometimes you're like, 'It's just too soon to do it.' But it's been 15 years." In October 2019, Chabert was asked if a sequel would be happening to which she replied: "I don't know. I wish I had an answer for you, I feel like you need to start a petition," while saying she would "of course" revisit the character if given the chance as "it would be so much fun to revisit these women and see where they are now."
In April 2020, Lohan was once again asked about the sequel by David Spade and confessed she had been hanging on to the idea of coming back to doing movies with that project "for a really long time" but that it was out of her hands. "To work with Tina [Fey], and the whole crew again, and Mark Waters. That was really what I wanted. I was excited to do that. But that's all in their hands really," she concluded. A few days later, McAdams also expressed interest in reprising her role in a sequel, after having declared in previous years she would be up for it as long as Fey was on board, "She's our master-in-chief on this one. So, if she's into it, then I'm into it." Bennett then reacted to his co-stars by saying, "I was extremely excited when I heard Rachel [McAdams] say she'd love to play Regina George again because I've talked to over half the cast, including Lindsay [Lohan], and we all feel the same way", continuing, "We'd love to bring these beloved characters back to life at some point." In an August 2020 interview on the podcast Unspooled, director Mark Waters discussed an idea for a sequel where the main characters from the original movie would now be young mothers serving together in a parent–teacher association, adding that its development is entirely up to Fey wanting to write a screenplay. A possible sequel was also questioned by Katie Couric while moderating a virtual reunion with the film's cast on October 3, 2020. Bennett then said in an interview he thought the virtual reunion "opened the door" for a sequel.
In August 2022, Franzese talked about a potential sequel or reboot, "I would absolutely love it. And I would do it in any form whatsoever. This movie brings people so much joy. [...] I mean, I want to do a whole movie with the whole cast. We all play different characters. People would love that, you know? Tina Fey's got that power and she ain't pulling the trigger. So I don't know who else could do it." He revealed he was writing his own script and would try to pitch it to Fey as they approached the film's 20th anniversary. In November 2022, Caplan was asked about a Mean Girls reboot and, although she was unsure about what was left of the story, she stated she would "of course" want to be a part of it: "I would be an idiot not to join." That same month, Seyfried interviewed Lohan for Interview magazine and expressed again their desire to work on a sequel but found it unlikely to happen at that moment due to the development of the movie musical. Meanwhile, during an interview on The Tonight Show Starring Jimmy Fallon, Chabert also shared a pitch where their characters' kids would become the "new mean girls". In early 2023, Seyfried stated all four actresses would like to reunite on set, suggesting potential roles as the mothers of their characters in the movie musical. In January 2024, Fey said they tried to bring back all four actresses for the movie musical but "it didn't come together". When asked about a possible sequel, she responded: "I have a feeling Paramount would love that. I have not really thought much about that. To me, part of why the stakes are so high in the story is because everyone's so young and feelings are huge, love is huge and friendship is huge in a way [that it isn't with] middle-aged moms. I love writing about middle-aged people, but I don't know."
