Following his graduation from high school, Corbett moved to California where he toiled in a steel factory for six years. During his time as a boilermaker in the factory, Corbett spent a year training to become an L.A. County Deputy Sheriff, but ultimately failed. He stopped working at the factory when he got injured and attended Cerritos College in Norwalk, California where he took acting classes and studied hair dressing for a year. He became a licensed hair stylist in 1986. He then landed a Samsung commercial, and after three years he had already starred in 50 national commercials. Aside from acting, Corbett has since, more seriously, pursued a career in music, releasing two country albums to date. Corbett has been in a long-time relationship with former actress Bo Derek since 2002.
