Davis first appeared on television in 1962. He portrayed Pvt. Roger Gibson in the ABC television series The Gallant Men. In 1963, he co-starred with Richard Egan in the NBCWestern drama Redigo, which was the renamed second season of the previous Empire television series, both set on a ranch in New Mexico. In 1964, Davis appeared in one episode of The Twilight Zone, "Spur of the Moment", co-starring Diana Hyland, and had a supporting role in the 1964 filmRide the Wild Surf. He guest-starred twice in the western TV seriesBonanza: he played Harold Stanley in 1966 and he portrayed Bert Yates in 1971. From 1968 to 1970, Davis garnered attention playing multiple characters on the daytime Gothic soap opera, Dark Shadows. He played Peter Bradford, Jeff Clark, Ned Stuart, Dirk Wilkins, and Charles Delaware Tate. In 1971, Davis narrated the voiceover theme sequence for the western series Alias Smith and Jones, starring Pete Duel as Hannibal Heyes/Joshua Smith and Ben Murphy as Jedidiah "Kid" Curry/Thaddeus Jones. He also appeared in one of the episodes as slick gunfighter Danny Bilson. Bilson has the distinction of being the only character kind-hearted Kid Curry was ever driven to kill during the series. Also in 1971, he appeared in season 12 episode 17 of NBC's Bonanza. When Pete Duel committed suicide at the end of 1971, Davis replaced him as Hannibal Heyes. However, after Davis completed just seventeen episodes, it was clear the show would never achieve the same level of popularity as it had with Pete Duel. The series subsequently ended in 1973. Competition from NBC's popular Flip Wilson Show siphoned the show's ratings. Davis continued to act in guest-starring roles on TV series throughout the 1970s, as well as the occasional film appearance in movies such as Killer Bees, Nashville Girl, Ruby and Aspen, and he has been the voiceover artist for thousands of TV and radio commercials.
