He was also nominated for the Academy Award for Best Live Action Short Film in 1994 for the short film Kangaroo Court. He is the son of actress Patty Duke and was adopted in 1972 by her then-husband, actor John Astin.

## Early life

Astin was born in Santa Monica, California, on February 25, 1971, the son of actress Patty Duke (1946–2016) and Michael Tell (born 1951). At the time, it was incorrectly reported that entertainer Desi Arnaz Jr. was his biological father. Tell is a writer, music promoter, and publisher of the newspaper The Las Vegas Israelite. When Duke became pregnant, she was unsure whether Arnaz, Tell, or actor John Astin was the father, and Tell offered to marry her as a way out of the scandal. The marriage lasted only 13 days in 1970, ending before Astin was born.
In 1972, Duke married John Astin. When the wedding guests were invited to speak, 18-month-old Astin looked at John and cried, "Daddy!", to which the Episcopal priest performing the ceremony remarked, "Well, that about does it!" John subsequently adopted Sean. In 1973, Duke gave birth to Astin's brother Mackenzie Astin, who also became an actor. Duke and John Astin divorced in 1985. Duke married Mike Pearce in 1986, and they adopted a son, Kevin, in 1989. When Astin was 14, Duke told him that Arnaz was his biological father. Almost a decade later, in 1994, Astin met Tell's niece, who suggested that Astin get a paternity test. Tell was found to be his actual biological father. Astin developed close relationships with all three, saying: "Desi Arnaz Jr. loves me, and I love him." Astin considers John his father, as John raised him. Astin is also close to his stepfather, Mike Pearce, saying, "I can call any of them on the phone any time I want to. John, Desi, Mike, or Papa Mike ... my four dads."
Astin is of German and Irish ancestry through his mother, and Jewish ancestry through his biological father. Astin attended Catholic school and later became a Protestant.
Astin attended the Crossroads High School for the Arts and undertook master classes at the Stella Adler Conservatory in Los Angeles. He graduated cum laude from UCLA with a B.A. in History and English (American literature and culture). An alumnus of Los Angeles Valley College, Astin served on the school's board of directors of the Patrons Association and the Arts Council.

## Career
### Early career

Astin's first acting role was in a 1981 television film titled Please Don't Hit Me, Mom, in which he played an 8-year-old child with an abusive mother (portrayed by his real-life mother Patty Duke). Astin made his film debut at the age of 13 as Mikey in The Goonies (1985).
After The Goonies, Astin appeared in several more films, including the Disney television film The B.R.A.T. Patrol, opposite Nia Long, Tim Thomerson, and Brian Keith; Like Father Like Son (1987); White Water Summer with Kevin Bacon (1987), The War of the Roses (1989); the World War II film Memphis Belle (1990); Toy Soldiers (1991); Encino Man (1992); and the college football biopic Rudy (1993), about the life-changing struggles and rewards of the titular character, Daniel Ruettiger.
In 1994, Astin directed and co-produced (with his wife, Christine Astin) the short film Kangaroo Court, which received an Academy Award nomination for Best Live Action Short Film. Astin continued to appear in films throughout the 1990s, including the Showtime science fiction film Harrison Bergeron (1995), the Gulf War film Courage Under Fire (1996), and the Warren Beatty political satire Bulworth (1998).

### The Lord of the Rings

In the early 2000s, Astin played Samwise Gamgee in Peter Jackson's The Lord of the Rings film trilogy, consisting of The Fellowship of the Ring (2001), The Two Towers (2002), and The Return of the King (2003). Many awards were bestowed upon the trilogy, particularly its final installment, which earned eleven Academy Awards, including Best Picture. Astin received seven award nominations for his own performance, and won five, including the Saturn Award, the Sierra Award, the Seattle Film Critics Award, and the Utah Film Critics Award (all for Best Supporting Actor), and the Visual Effects Society Award for Outstanding Performance by a Male or Female in an Effects Film. The Return of the King cast as an ensemble received awards from the National Board of Review of Motion Pictures, the Screen Actors Guild, the Broadcast Film Critics Association, and received a Gold Derby Award. Throughout the filming process, Astin became close friends with several cast members, particularly Elijah Wood. Astin's daughter, Alexandra, is in the closing scene of The Return of the King, playing his onscreen daughter, Elanor.
While working on The Lord of the Rings, Astin persuaded a number of fellow cast and crew members, including director Peter Jackson, to assist him in making his second short film, The Long and Short of It. The film, which takes place on a street in Wellington, New Zealand, premiered at the 2003 Sundance Film Festival and can be found on the DVD for The Two Towers, along with a "making of" video.
In 2004, Astin released There and Back Again (ISBN 0-312-33146-0), a memoir (co-written with Joe Layden) of his film career with emphasis on his experiences during production of The Lord of the Rings trilogy. The title is derived from the title of J. R. R. Tolkien's novel The Hobbit, as well as the fictional book written by Bilbo Baggins in The Lord of the Rings.

### After The Lord of the Rings

Since The Lord of the Rings, Astin has continued to work in film and television. His film roles have included the Adam Sandler comedies 50 First Dates and Click. Astin played the role of Malibu High School principal Mike Matthews in the film Smile.
In television, Astin guest-starred as Lynn McGill in ten episodes of the fifth season of the Fox drama 24. He also appeared in the made-for-TV films Hercules and The Colour of Magic and in episodes of Monk, Las Vegas, My Name Is Earl (in which he parodied his 1993 film Rudy with co-stars Charles S. Dutton and Chelcie Ross), and Law & Order, among other shows. Astin directed a 2003 episode of the TV series Angel, titled "Soulless". He played the enigmatic Mr. Smith on the second season of the Showtime series Jeremiah.
Astin's career has also expanded to include voice-over roles. He narrated the American version of the Animal Planet series Meerkat Manor, and voices the title character in Special Agent Oso which aired on Playhouse Disney from 2009 to 2011 and Disney Junior from 2011 to early 2014. Astin's other voice work includes Balto III: Wings of Change, in which he voiced Kodi, a teenage husky who is the son of the titular character, and the video game Kingdom Hearts, in the latter of which he provided the voice of Hercules, replacing actor Tate Donovan, who was unavailable but would return for Kingdom Hearts II. Astin also voiced Raphael in the Teenage Mutant Ninja Turtles animated series on Nickelodeon, which premiered on September 29, 2012, running for five seasons and 124 episodes, and ending on November 12, 2017.
In 2010, Astin joined the Stella Adler Los Angeles Theatre Collective acting company.

His wife held the Miss Indiana Teen USA title in 1984. Alexandra had a small cameo role in The Lord of the Rings: The Return of the King as Elanor Gamgee, Astin's character's daughter, and appears in Bad Kids of Crestview Academy as Ethel Balducci.
Astin has a tattoo on his ankle of the word "nine" written with the Tengwar script, commemorating his Lord of the Rings involvement and his character's membership in the "Fellowship of the Ring". Seven of the eight other actors (Elijah Wood, Sean Bean, Billy Boyd, Ian McKellen, Dominic Monaghan, Viggo Mortensen and Orlando Bloom) all have the same tattoo. John Rhys-Davies' stunt double, Brett Beattie, has the tattoo as well.
In an August 2013 interview, Astin said that he is a Lutheran Christian, having been "baptized in my wife's Lutheran church". "I don't know if I'm a very good [Christian] but I'm praying the forgiveness thing is legit," Astin said in an interview.
In January 2015, Astin completed the Dopey Challenge at the Walt Disney World Resort which involves running a 5k, 10k, half-marathon and full marathon on four consecutive days.
