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.

During the 2004 United States presidential election, Astin backed Senator John Kerry and participated in Kerry's campaign rally in Portland, Oregon, as the opening speaker.

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 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 (11) 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.

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).

In television, Astin guest-starred as Lynn McGill throughout 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. He 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 married Christine Harrell on July 11, 1992. They have three daughters: Alexandra (born November 27, 1996), Elizabeth (born August 6, 2002), and Isabella (born July 22, 2005), all having the middle name Louise. 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.

After The Goonies, Astin appeared in several more films, including the Disney made-for-TV movie, 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.

Astin's first acting role was in a 1981 television movie 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). He made his film debut at the age of 13 as Mikey in The Goonies (1985).

On August 5, 1972, Duke married actor John Astin, after having been in a relationship with him for two years. When the wedding guests were invited to speak, 18-month-old Sean looked at John and cried, "Daddy!", to which the Episcopal priest performing the ceremony remarked, "Well, that about does it!" Astin subsequently adopted Sean. In 1973, Duke gave birth to Astin's half-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.

Sean Patrick Astin (né Duke; born February 25, 1971) is an American actor, voice actor, director, and producer. His acting roles include Samwise Gamgee in The Lord of the Rings trilogy (2001–2003), Mikey Walsh in The Goonies (1985), Daniel Ruettiger in Rudy (1993), and Bob Newby in the second season of Stranger Things (2017).

Astin was born in Santa Monica, California, the son of actress Patty Duke (1946–2016) and Michael Tell. However, at the time, it was erroneously reported that entertainer Desi Arnaz Jr. was his biological father. During that time, Duke also had a sexual relationship with Michael Tell, a writer, music promoter and publisher of the newspaper The Las Vegas Israelite. When Duke became pregnant, she was unsure whether Arnaz or Tell was the father, so Tell offered to marry her as a way out of the scandal. The marriage only lasted 13 days in 1970, and ended long before Astin was born.
