William McNamara's journey in the entertainment industry began at the prestigious Lee Strasberg Theatre and Film Institute, where he honed his craft and went on to accumulate an impressive filmography of over 165 film and television appearances.
His early career was marked by notable roles in films such as Dream a Little Dream (1989) alongside Corey Feldman and Corey Haim, and Stella (1990) starring Bette Midler.
The 1990s proved to be a pivotal decade for William, as he delivered standout performances in a range of genres. He brought depth and nuance to his portrayal of Derek Wolfe Jr in the Ernest R. Dickerson-directed thriller Surviving the Game (1994),sharing the screen with a talented ensemble cast including F. Murray Abraham, Gary Busey, Rutger Hauer, and John C. McGinley.
That same year, he teamed up with Gary Busey once again, this time in the Navy comedy Chasers (1994),directed by Dennis Hopper, alongside Tom Berenger.
However, it was his chilling portrayal of Peter Foley, a copycat serial killer, in the psychological thriller Copycat (1995) that cemented his reputation as a versatile and talented actor. The film also starred Sigourney Weaver, Dermot Mulroney, and jazz musician Harry Connick Jr.
William's impressive resume continued to grow with appearances in Stag (1997),alongside Andrew McCarthy and John Stockwell, and The Brylcreem Boys (1998),opposite Gabriel Byrne.
Interestingly, William's first feature film role was in the cult classic Opera (1987) directed by the renowned Dario Argento. Despite his on-screen personas, William is a kind spiritualist and passionate animal rights activist, dedicating his time, energy, and resources to the plight of dolphins and small whales in Japan, as well as animal rescue efforts, Kundalini, and Yoga.
Like his co-star Henry Rollins in Time Lapse (2001),William is an advocate for causes close to his heart, actively pursuing his passions and getting his hands dirty in the process.
