In
Colt .45 he played Christopher Colt, a government undercover agent who masquerades as a Colt 45 revolver salesman traveling throughout the
Old West. Preston also played the role of Christopher Colt in 1958 and 1959 in four episodes relating to "The Canary Kid" of the ABC/WB
Sugarfoot series. Preston appeared in "The Saga of Waco Williams" on
Maverick. Preston played some 20 roles in television and films from 1957 to 1991. He left acting in 1959 to become an executive in a firm that sold airplanes and provided air charter services. He attributed the change to a difference in income and the way he was treated as an actor. "It wasn't just the hard work and low pay," he said. "The studio did petty things that added insult to injury. I got tired of being treated like an ingenue." He said that he thought he was going to make feature films when he signed with the studio, and he felt that continuing in a TV series would harm his career. Following his departure from
Colt .45, he went to Europe, where he appeared in numerous
Spaghetti Westerns, including
A Man Called Sledge and the 1968 film
Anzio, about the
World War II Battle of Anzio. Preston played Logan in another 1968 film,
Wrath of God; he was then cast in 1969 as Marshal Johnny Silver in
Death Knows No Time. He appeared on episodes of NBC's
Bonanza and ABC's
Starsky & Hutch. His last screen appearance was in a supporting role in the 1990 film version of
Captain America. == Personal life ==
