Acting Career

Matheson started appearing on TV while he was just a teenager. During this time, Timothy starred in Window on Main Street as Roddy Miller. The film was a nostalgia comedy, and Matheson was featured on it at the age of 13. Apart from conventional acting, Matheson's voice has also been used for voice-over work on Jonny Quest. Apart from that animated series, Matheson's voice has also been employed in various other animations, including Space Ghost and Sinbad Jr. and his Magic Belt.

In 1969, Matheson became a cast member in the NBC TV show The Virginian, where he played the role of Jim Horn. After starring in The Virginian, Matheson then took on a guest role in Night Gallery. In 1972, Matheson was in Bonanza, where he played various roles in the TV series' final season. Matheson played Phil Sweet, a motorcycle cop in Magnum Force. Years later, Timothy was again featured on various CBS films, including Three for the Road, a short-lived drama, Leave It to Beaver, and My Three Sons.

In 1976, Matheson took advantage of an opportunity to star in an NBC TV show called The Quest. In the series, which encompassed 15 episodes, Timothy starred with Kurt Russell, a renowned and well-respected actor. The storyline was about two young men searching for their sister's whereabouts in the American West because the sister was held captive. After some time away from acting, Matheson was again seen on screen. He had one of his most special rules when he co-starred alongside John Belushi in National Lampoon's Animal House. This was before the two actors acted together again in 1941. In furthering his acting career, Matheson starred in Fletch and Up the Creek, both comedy films.

Other Ventures

Aside from acting, Matheson tried to put his entrepreneurial abilities into practice with Dan Grodnik when they purchased National Lampoon. During this time, the magazine was entangled in a severe financial crisis. However, it was rather unfortunate that Matheson and his business partner could not bring back the magazine to a state of financial stability. As a result, the business partners resorted to selling it in 1991. In addition to being cast in numerous films and TV series, Matheson has also directed various episodes of certain shows, including Burn Notice and Third Watch. Tim has also referred to Suits, Ed, Criminal Minds, The Twilight Zone, White Collar, Cold Case, White Collar, Without a Trace, Shark, The West Wing, The Good Guys, and Psych. Tim likes to get involved in politics because he has extreme opinions about society. He was raised to be equal and welcoming to all people, and he described his upbringing in Smashing Interviews.
