[8] He changed his name to Brad Dexter, playing a villainous detective in The Asphalt Jungle (1950) and landing a role in Fourteen Hours (1951).

Dexter's breakthrough role was as a villain in RKO's The Las Vegas Story (1951), starring Victor Mature and Jane Russell.

Dexter then shifted largely into television, appearing in episodes of Climax!, The Gale Storm Show, How to Marry a Millionaire, Pursuit, Studio One in Hollywood, Wagon Train, Bat Masterson, Have Gun – Will Travel, Zane Grey Theatre, Behind Closed Doors, Cimarron City, Yancy Derringer, This Man Dawson, 77 Sunset Strip, Colt 45, The Man from Blackhawk, Tightrope, Mr. Lucky, Bat Masterton, and Wanted: Dead or Alive, starring Steve McQueen.

Even after embarking into television, Dexter still made the occasional feature film, such as Last Train from Gun Hill (1959), directed by John Sturges, and Vice Raid (1959), and was second billed in 13 Fighting Men (1960).

He could be seen in It Started in Tokyo (1961), The George Raft Story (1961) (playing Bugsy Siegel), X-15 (1962) with Charles Bronson and Johnny Cool (1963).

Dexter supported Yul Brynner again in Taras Bulba (1962), Kings of the Sun (1963) (from the producers of Magnificent Seven), and Invitation to a Gunfighter (1964).

In 1963, Dexter was cast as California Supreme Court Justice David S. Terry in "A Gun Is Not a Gentleman" on the syndicated anthology series, Death Valley Days, hosted by Stanley Andrews.

[10] After Dexter appeared in Bus Riley's Back in Town (1965), he made another film with Sinatra, Von Ryan's Express (1965).

Dexter returned to acting with roles in Jory (1973), Shampoo (1975), Vigilante Force (1976), The Private Files of J. Edgar Hoover (1977), House Calls (1978) and Winter Kills (1979), and guest parts on McCloud, Kojak, S.W.A.T., Project U.F.O., and The Incredible Hulk.
