Trivia: Sean Astin had starred in ten movies, directed a short film, and formed his own production company all before his 21st birthday. The elder son of actress Patty Duke and actor/director John Astin, he knew the hazards of Hollywood life: As a popular child star, Astin refrained from drinking, drugs, and narcissism. He juggled acting with attending classes at Crossroads High School for the Arts and Los Angeles Valley College, eventually graduating cum laude from the University of California at Los Angeles with dual degrees in History and American Literature and Culture. When his younger brother, fellow kid actor Mackenzie Astin, temporarily fled Los Angeles to pursue journalism, Astin doggedly remained in town -- he once half-heartedly considered a law career, but could never part with being an entertainer. Astin was born in Santa Monica, CA, on February 25, 1971. His famous parents actively supported his childhood ambition to become an actor, and Astin was cast in TV specials, movies, and even series until 1983. Barely a year later, screenwriter Steven Spielberg handpicked the 13-year-old Astin to star as Michael "Mikey" Walsh in Richard Donner's children's adventure film The Goonies (1985). Astin earned his first Young Artist Award for his work on the film and went on to act in a host of teen pictures. He headlined the Disney Channel television movie The B.R.A.T. Patrol (1986), joined Kevin Bacon for the wilderness adventure White Water Summer (1987), and appeared with Dudley Moore and Kirk Cameron in the comedy Like Father, Like Son (1987).In 1988, Astin directed his first short film, a Vietnam picture about the unexpected relationship between an American GI and a Viet Cong soldier titled On My Honor. Astin's own production company, Lava Entertainment, financed the film. While continuing to develop projects through Lava Entertainment, Astin starred with Dermot Mulroney in 1989's Staying Together. He won his second Young Artist Award for his performance in the picture. Also in 1989, Astin portrayed the teenage son of feuding couple Kathleen Turner and Michael Douglas in Danny DeVito's The War of the Roses. He finished off the '80s by enlisting in the all-star cast of Michael Caton-Jones' World War II drama Memphis Belle (1990). The film -- which also features Matthew Modine, Harry Connick Jr., Billy Zane, and Eric Stoltz -- followed the crew of the Memphis Belle bomber on their harrowing final run over Germany. Astin's stocky build and comic timing lent well to his incarnation as the group's tail gunner, Sergeant Richard "Rascal" Moore. When Astin initially lost the lead role in his next picture, Toy Soldiers (1991), to Wil Wheaton, he treated the film's director, Dan Petrie Jr., to a screening of Memphis Belle. Petrie was so impressed by his work that he relegated Wheaton to a supporting part and cast Astin as Toy Soldiers' hero, a rebellious student who saves his prep school from South American terrorists.In the spring of 1992, Astin starred with Pauly Shore and Brendan Fraser in Encino Man, a comedy about two California high school students who discover a caveman. He then reunited with Dermot Mulroney in the drama Where the Day Takes You (1992), which also stars Will Smith, Christian Slater, Lara Flynn Boyle, and Ricki Lake. 1993 saw Astin play the title character in Rudy, the memorable film about a tenacious boy determined to play football for Notre Dame despite the fact that he is too small. Football coaches around the United States still show the film before games to inspire their players, and, to this day, strangers still chant "Rudy! Rudy!" when they spot Astin on the street.After filming Safe Passage (1994) with Susan Sarandon and Sam Shepard, Astin appeared in the independent film The Low Life (1995), for which he won the Best Actor Award at the 1995 Fort Lauderdale Film Festival. That same year, he wrote, directed, and produced his second short film, Kangaroo Court. The picture tells the story of a police officer who is put on trial by an inner-city gang and stars Gregory Hines and Michael O'Keefe. It earned Astin an Academy Award nomination for Best Short Film (coincidently, John Astin was nominated in the same category for his film Prelude in 1969).Astin continued to work steadily throughout the '90s. In 1995, he starred in Showtime's adaptation of Kurt Vonnegut Jr.'s futuristic short story Harrison Bergeron. In 1996, he made a cameo as a doomed soldier in the first feature film to depict Desert Storm, Edward Zwick's Courage Under Fire. In 1997, he directed and starred in an episode of HBO's Perversions of Science called "Snap Ending" and was one of several narrators in the Academy Award-winning Holocaust documentary The Long Way Home. In 1998, Astin took a small role in Warren Beatty's Bulworth and began work on a string of independent films -- including Boy Meets Girl (1998), Dish Dogs (1998), Kimberly (1999), Deterrence (1999), and Icebreaker (1999). The decade also brought changes to Astin's personal life. On July 11, 1992, he married Christine Astin (born Harrell) at Patty Duke's Idaho farm. The couple met when she worked at Astin's talent agency and they co-founded Lava Entertainment together. Then, in 1994, Astin underwent DNA testing that revealed rock promoter Michael Tell to be his biological father (Patty Duke and Tell had been briefly married before her engagement to John Astin). Though the actor is friendly with Tell, he still considers those who raised him to be his parents. Two years later, Astin and his wife had their first child, Alexandra Louise, in November of 1996. In the summer of 1999, Astin landed the coveted part of portly hobbit Samwise "Sam" Gamgee in Peter Jackson's highly anticipated three-film adaptation of J.R.R. Tolkien's The Lord of the Rings trilogy. Auditions for the role were held over several months in every English-speaking country in the world. Astin's father had appeared in Jackson's horror film The Frighteners, and the veteran actor's fondness for the director made Astin determined to get the part. When he found that his only competition was an overweight English thespian, Astin gained 30 pounds to secure the role. All three installments of the trilogy -- The Fellowship of the Ring (2001), The Two Towers (2002), and The Return of the King (2003) -- were filmed simultaneously over an 18-month period in New Zealand. Astin's wife and daughter accompanied him to the shoot and Alexandra made her acting debut as a young hobbit in Sam Gamgee's family. The couple had a second child, Elizabeth Louise, between the release of the first and second films.After the success of the Lord of the Rings franchise, Astin kept busy with a slew of projects throughout the 2000s, like 50 First Dates, Click, and an arc on the TV series 24. Astin would also do extensive voice acting in the 2000s and 2010s, on kids shows like Special Agent Oso and Teenage Mutant Ninja Turtles.

Trivia: American actress Patty Duke (born December 14, 1946) was groomed almost from infancy for a starring career by her manager/guardian John Ross. She studied at the Quintano School for Young Professionals and earned her Equity card at age seven, appearing in numerous TV productions and in such Hollywood films as I'll Cry Tomorrow (1955), The Goddess (1958) (playing young Kim Stanley, the "Marilyn Monroe" character in that film), and Happy Anniversary (1959). Duke also appeared as a quiz-show contestant, and was later compelled to testify as to her honesty during the cheating scandals of 1958 and 1959. Just before her 13th birthday, Duke made her stage debut in the role of Helen Keller in The Miracle Worker; the production won the girl instant stardom and later an Academy Award for the film version of Miracle Worker (1962). Manager John Ross very carefully monitored Duke's public appearances, making certain the world saw her as a sweet, uncomplicated young lady. The truth was that Duke was terribly unhappy, feeling pressured into performing and into suppressing her own emotions. That's not what the world saw in the three seasons of The Patty Duke Show (1963-1966), a sitcom wherein the young actress literally talked to herself in the dual role of cousins Patty and Cathy Lane. She became cynical with stardom in a hurry, and in a bold act of defiance, 18-year-old Duke married a man twice her age, director Harry Falk Jr. Her first grown-up role as a Judy Garland type in Valley of the Dolls (1967) was panned, and it was suggested that she'd lost her talent. The next few years she was cast in a series of unsuccessful films but made a strong comeback with the 1969 TV movie My Sweet Charlie, which won her the first of three Emmys; the others being for the miniseries Captains and the Kings(1976) and a remake of The Miracle Worker (1979) in which she played the role of Annie Sullivan, co-starring with Melissa Gilbert as Helen Keller. In 1972 she married actor John Astin. He raised her son, Sean Astin (actually the biological son of music promoter Michael Tell), as his own; they had Mackenzie Astin together. Duke also briefly changed her professional name to Patty Duke Astin. The Astins worked together prolifically for the duration of their marriage (which eventually ended in divorce). Building up her self-confidence and completely rebuilding her reputation in the '80s, Patty Duke served from 1985 through 1988 as president of the Screen Actor's Guild (the second woman to do so), starred in three separate network sitcoms, and wrote her harrowing best-selling memoirs, Call Me Anna, which in 1990 was adapted into a TV movie that she co-produced and starred in.In 2002, Duke returned to the stage to play Aunt Eller in a production of Oklahoma!, and appeared as a guest on The Oprah Winfrey Show in 2007 to discuss living with bipolar disorder. The actress replaced Carol Cane as Madame Morrible in the San Francisco production of Wicked in 2009, and joined the cast of The Protector (a short-lived drama from Lifetime) in 2011. Her final role was in a 2015 episode of the Disney channel show Liv and Maddie, fittingly playing a set of identical twins. Duke died in 2016, at age 69.
