Langton's early stage experience included acting in productions of the
Mountain Play Association in California and the
Pasadena Playhouse. He performed on Broadway in
Harbor Lights (1956). Making his movie bow in 1941, Langton became a contract player at
Metro-Goldwyn-Mayer, frequently appearing in war films. Later, Langton was seen in character parts or supporting roles in such films as
The Incredible Shrinking Man (1957). He also was a voice actor on
Lux Radio Theatre from 1942 to 1954. Langton began appearing on television in 1951 in a series called
The Web. His first regular role was that of Walter Dennis on the daytime series
The Brighter Day. He also made five guest appearances on
Perry Mason from 1958 to 1962, three of which were as prosecuting attorneys. But it was the role of Leslie Harrington on the prime time serial
Peyton Place (1964–68) that finally gave him a level of stardom. After he was written out of the series, he appeared in half a dozen other programs including
It Takes a Thief (1968),
Ironside (TV series) and, in his final role,
Emergency!, before retiring due to ill health. == Personal life and death ==
