High School Musical is a 2006 American musical television film directed by Kenny Ortega and written by Peter Barsocchini. The 63rd Disney Channel Original Movie (DCOM) and first installment of the High School Musical film series, the film stars Zac Efron, Vanessa Hudgens, Ashley Tisdale, Lucas Grabeel, Alyson Reed, Corbin Bleu, and Monique Coleman. In High School Musical, Troy Bolton (Efron), the basketball team captain, and Gabriella Montez (Hudgens), an academically gifted transfer student, try out for the lead parts in their school musical, causing division among the school's cliques.
 Development for the film began after Disney network executives wanted to replicate the critical and viewership success of standalone musical episodes in their television series Even Stevens (2000–2003) and That's So Raven (2003–2007). Principal photography for High School Musical primarily took place in Utah, with filming locations including East High School, Murray High School, and Salt Lake City. Additional filming took place in Los Angeles. The film has been described by Barsocchini and numerous critics as a modern adaptation of Romeo & Juliet.
 Upon its release on January 20, 2006, as part of Disney Channel's "Gotta Sing, Gotta Dance Week" block, it became the most commercially successful DCOM ever produced. In the U.S., High School Musical generated 7.7 million viewers in its premiere broadcast, breaking the then-record for the highest premiere for the network. Internationally, the film also saw considerable success; as of 2019, over 225 million unique viewers were calculated as watched High School Musical. The film received generally mixed reviews from critics, with praise for its cast and music but criticism for its sentimentality; it was more positively received by audiences. The film's soundtrack was commercially and critically successful, reaching atop the U.S. Billboard 200, with its lead single, "Breaking Free", reaching number four on the U.S. Billboard Hot 100. Two sequels, High School Musical 2 and High School Musical 3: Senior Year, were released in August 2007 and October 2008 respectively.
 On New Year's Eve, high school juniors Troy Bolton and Gabriella Montez meet at a ski lodge party during winter break. The two are called upon to sing a duet together for karaoke ("Start of Something New"). Returning to school after the break, Troy sees Gabriella in his homeroom. She explains that she has just moved to Albuquerque, New Mexico, and transferred to East High School over the break. As Troy shows Gabriella around the school, drama club president Sharpay Evans assumes that Gabriella is interested in auditioning for the school musical. Wanting to eliminate the competition, Sharpay discovers Gabriella's past academic achievements, and anonymously informs scholastic decathlon captain Taylor McKessie of them, so she will recruit Gabriella for the team. Taylor and Gabriella become friends over their shared interests.
 During a basketball practice, Troy is distracted by thoughts of Gabriella and the idea that he might enjoy singing in addition to basketball ("Get'cha Head in the Game"). Gabriella and Troy go to the musical auditions where Sharpay and her twin brother Ryan Evans perform "What I've Been Looking For". However, Troy and Gabriella are hesitant to audition. When Gabriella gains the confidence to step forward once the auditions are unofficially declared "over", Troy offers to sing with her. However, drama teacher Ms. Darbus tells them they are too late and leaves. Kelsi Nielsen, the musical's composer, drops her music sheets on the stage; Troy and Gabriella rush to help her and sing the same song together. Overhearing their performance, Ms. Darbus gives them a callback audition.
 When the callback list gets posted, Sharpay is furious that she has competition for the lead role, while the Wildcats basketball team is shocked that Troy has auditioned. After finding out that Troy can do activities outside his clique, other students confess their secret passions and talents ("Stick to the Status Quo"). This alarms Taylor and Troy's best friend Chad Danforth. Taylor and Chad come up with a plan to divert Troy and Gabriella from singing in the musical so they can focus on their upcoming competitions.
 In the locker room, Troy is tricked by his teammates into saying that Gabriella and the audition are not important to him. Gabriella watches this via a hidden webcam that the scholastic decathlon team has set up. Upset by Troy's perceived betrayal and callous disregard for her ("When There Was Me and You"), Gabriella decides to not audition for the musical, and distances herself from Troy. Troy, confused by Gabriella's behavior, is unable to concentrate on the game, while Gabriella is low in spirits. Realizing their mistake, Chad and the basketball team tell Troy what happened and offer to support him in the callbacks. Taylor also explains to Gabriella that she was wrong but Gabriella dismisses this, believing Troy meant what he said. That evening, Troy goes to Gabriella's house where he explains the truth and they reconcile, determined to audition for the musical.
 Overhearing Gabriella and Troy rehearse, Sharpay asks Ms. Darbus to move the callbacks so they start at the same time as both Troy's championship game and Gabriella's scholastic decathlon competition. Kelsi overhears the conversation, and both the basketball and decathlon teams make a plan together. On the day of the competitions, Taylor and Gabriella use the school's computers to delay the championship game by hacking the power in the gym and causing a chemical reaction that forces an evacuation during the decathlon. Troy and Gabriella rush to the auditorium as Sharpay and Ryan finish their callback song ("Bop to the Top"). After Gabriella and Troy successfully perform their song "Breaking Free", Ms. Darbus gives them the lead roles, making Sharpay and Ryan understudies. Both teams win their respective competitions, and the entire school gathers in the gym to celebrate ("We're All in This Together"). Chad asks Taylor out, and Sharpay makes a truce with Gabriella.
 In a post-credits scene, Zeke Baylor paces alone in the gym, when Sharpay runs in, declaring that the cookies he had given her that she had initially rejected are "genius". She hugs him, and he says he will make her a crème brûlée. Zeke smiles in victory.
 The soundtrack for the film was released on January 10, 2006, and debuted at number 133 on the Billboard 200, selling 7,469 copies in its first week. In the album's third week, for the chart dated February 11, 2006, it climbed to number ten, subsequently rose to number one on the Billboard 200 twice (on March 1 and 22) and had shipped 3.8 million copies as of December 5, 2006. Out of those copies, more than three million copies had been sold by August 2006; it was certified quadruple platinum by the RIAA.
 Disney Channel produced a musical episode of its original sitcom Even Stevens, which aired in 2002, and the success of the episode among the show's audience led to network executives asking series executive producers David Brookwell and Sean McNamara to also produce a musical episode of their other comedy series That's So Raven. The success of the musical format on both Even Stevens and That's So Raven gave executives confidence in the appeal and interest of the musical genre, and led to the early development of the idea for High School Musical. Gary Marsh, then-president of Disney Channels Worldwide, stated that High School Musical would not have been developed if not for the success of the Even Stevens musical episode.
 Principal photography for High School Musical took place in Utah, with East High School and Murray High School used as locations, as well as Salt Lake City. Additional scenes were filmed in Los Angeles.[citation needed]
 Upon its premiere, the film attracted 7.7 million viewers. On Rotten Tomatoes, the film holds an approval rating of 65% based on 20 reviews, with an average rating of 5.7/10. The website's critics consensus reads: "High School Musical is brazenly saccharine, but it makes up for it with its memorable show tunes, eye-popping choreography, and appealing cast."
 Common Sense Media rated the film four out of five stars. Kevin Carr gave the film a score of three out of five, saying, "The filmmakers were just trying to tell a story. Sex, drugs and violence just didn't factor into that equation." On the other hand, David Nusair gave the film a negative review with a score of 1.5/4 saying, "...it's difficult to imagine even the most die-hard fan of musicals finding anything here worth embracing." Scott Weinberg also gave the film a negative review saying, "A schmaltzy little piece of obvious fluff that's directed in truly horrendous fashion and populated by cardboard characters who spit out simplistic platitudes and breathy pop tunes."

It created a sales record when 1.2 million copies were sold in its first six days, making it the fastest-selling television film of all time.

 Film Business Asia critic Derek Elley rated the adaptation three points out of ten and called the choreography by former Madonna dancer, Ruthy Inchaustegui, and songs "bland". However, Elley picked the three songs as "half-memorable": "the ballad 'Rainy Season' (梅雨季) [sung by] two lead[ing characters,] the glitzy 'Perfection' (完美) [by] the college rich-bitch[,] and [the] climatic 'I Can Fly' (我飛故我在), which doesn't quite succeed at being an anthemnal [sic], uplifting ballad."
