Perhaps West's most notable film work came in the 1996 film Space Jam, where he provided the voice of both Bugs Bunny and Elmer Fudd. West reprised the roles of Bugs and Fudd in subsequent Looney Tunes feature-length films and returned as Fudd in the theatrically released Looney Tunes: Back in Action. In 1998, West starred in the direct-to-video film Scooby-Doo on Zombie Island as Shaggy Rogers, becoming the second person to portray the character (the first being Casey Kasem).
