Although most famous for his role as “Ralph Hinkley” on the classic television series, “The Greatest American Hero”, William Katt is an accomplished actor, writer, director, producer who has appeared in over 120 movies, tele-films and TV roles.
Katt attended Orange Coast College before pursuing a career as a musician. Inspired by his father, he then started an acting career, appearing in summer stock and in small television roles. His earliest film credits include the role of a jock, Tommy Ross in Brian De Palma's 1976 horror film adaptation Carrie, which allowed Katt to make a name for himself. In 1978, he appeared as Barlow, a young surfer, in the John Milius drama film Big Wednesday opposite Jan-Michael Vincent and Gary Busey. His mother in that film was his real-life mother, Barbara Hale.
The following year he took the role of Sundance Kid in the 1979 film Butch and Sundance: The Early Days. The role in Big Wednesday made him so well known in the surfing community that in 2004 he presented one of the Association of Surfing Professionals awards at their annual World championship tour ceremony to wild applause from the crowd of professional surfers. Katt explained in a 1979 interview with critic Roger Ebert that he was holding out only for parts which were personally interesting to him.
In December 1975, Katt auditioned for the part of Luke Skywalker in 1977's science fiction blockbuster Star Wars, and footage of his audition has been featured in many Star Wars documentaries. He was seriously considered for the role, which instead went to Mark Hamill, and Katt instead starred that year in First Love, playing a college student who experiences his first romantic relationship.
In 1981, Katt was cast as the title role in a filmed version of the Broadway musical comedy Pippin, which received mixed reviews. He won his best remembered role that year, however, as Ralph Hinkley, a mild-mannered schoolteacher given a superpowered suit by aliens on the television series “The Greatest American Hero”, a role he played until the show was canceled in 1983. Also starring veteran actor Robert Culp, the show was wildly popular however, and retains a cult fanbase. Its theme song, "Believe It or Not", penned by television soundtrack icon Mike Post, also became a big hit in the music charts. In 1982, due to the success of the first season of “The Greatest American Hero”, Katt signed to MCA and released a soft rock album, Secret Smiles under the name Billy Katt.
After “The Greatest American Hero”, Katt starred in Baby: Secret of the Lost Legend (1985), about explorers searching for apatosaurs in Africa; the cult horror/comedy film House (1986) (reprising his role for the third sequel, House IV in 1992), and played the recurring role of detective Paul Drake Jr. in the periodic Perry Mason TV movies of the late eighties. These co-starred his mother, Barbara Hale, who resumed her Della Street role from the original show, and Katt collaborated on some of the later scripts. Katt starred in the 1989 TV series “Top of the Hill” and made a guest appearance on the first episode of the short-lived 1991 series “Good Sports”.
Katt continues to appear on television and in supporting film roles, and also has branched out into voice acting. He appeared in an episode of “House” in 2006. In recent years, he has returned to genre work, with appearances in Andromeda and Justice League and roles in the award-winning film Gamers (2006), The Man from Earth (2007), and Alien vs Hunter (2007).
Katt attended and was a mentor at the 2nd annual HatcH audiovisual festival in Bozeman, MT in October 2005. HatcH is a film and arts festival whose mission is to provide mentorship, education, inspiration, and recognition to the next generation of creative innovators. In 2008, he started his own line of comic books, Catastrophic Comics, with the launch of the critically acclaimed book Sparks co-created with Christopher Folino.
Katt briefly appeared in Heroes season 3 in "The Butterfly Effect" as a nosy reporter investigating Ali Larter's character. He portrayed Jack Matheson in the thriller film, Mirrors 2. In 2010 during season 6, Katt guest starred as C.J. Payne's musician birth-father in the episode "Who's Your Daddy Now?" in the Tyler Perry comedy House of Payne.
Katt also has written a Greatest American Hero comic book and contributed to that series' Facebook page. In 2013, Katt played himself in the spoof film Paranormal Movie directed by Kevin Farley.
