As a child actor, Tim Matheson was billed under his fuller family name of Matthieson. His first weekly TV co-starring assignment was opposite Robert Young in the 1961 "dramedy" Window on Main Street. The young actor's voice became familiar to a generation of cartoon fans via his "role" as the title character in Hanna-Barbera's Jonny Quest. The handsome Matheson appeared on-screen during his maturation years on such western series as The Virginian, Bonanza, and The Quest. He remained busy in films during this period, scoring his biggest 1970s success as party animal Otter in National Lampoon's Animal House (1978). Matheson also kept his hand in the voiceover business, providing the truculent mutterings of "Blood" the dog in Harlan Ellison's A Boy and His Dog (1975) and recording the narration for the 1985 revival of Disney's Fantasia. His adult TV appearances have included weekly stints on the TV series Tucker's Witch (1982), Just in Time, (1988) and Charlie Hoover (1991). Turning to directing in 1985, Matheson has been active in episodic television, music videos and direct-to-cassette movies. In 1989, he became CEO of the National Lampoon Company, though he still manages to find time for the occasional acting assignment, appearing in everything from the theatrical feature Drop Dead Fred to the live-action prologue for one of the "thrill rides" at Disneyworld.
