West is best known for his voice-work on Ren & Stimpy, Doug and Futurama. His favorite characters are Philip J. Fry (Futurama) and Stimpy (Ren and Stimpy), both of which he originated. West's most notable film work was in Space Jam (1996) providing the voice of both Bugs Bunny and Elmer Fudd; he has provided the same voices for other Looney Tunes films and video games.
