Rainn Wilson lives in Los Angeles with his wife, fiction writer Holiday Reinhorn (Big Cats), and his son, Walter McKenzie Wilson who was born in 2004. He grew up in Seattle, Washington but graduated from New Trier H.S. in Winnetka, Illinois. After attending both Tufts University and the University of Washington, Rainn studied acting at NYU's graduate acting program and spent years doing theater both on and off-Broadway, on tours with the Acting Company and in region theatre including The Guthrie and Arena Stage.
Rainn co-created and directed The New Bozena, a sketch comedy and post-modern clown show which performed in New York and ended up doing a pilot presentation at Fox TV. He made his directorial debut with The New Bozena (2005), a short film based on the show.
After many years of working in TV and film, his breakthrough role happened, as Arthur, the odd love interest to the much older Frances Conroy on Six Feet Under (2001). His favorite role to date, however, is Bill Harris in the film, Baadasssss! (2003).
Rainn is a member of the Baha'i Faith.
