He was also in a decent movie occasionally, (had a small part in John Wayne's Stagecoach, and a major one opposite Humphey Bogart in The Treasure of the Sierra Madre) but he mostly did cheap westerns like Hot Lead, (1951) or embarrassing junk like The Monster That Challenged the World. (1957) His father was more famous than he was. Read his IMDB entry.
He died at 54 from bone cancer on February 15, 1973 in Shawnee, Oklahoma, where he was the manager of a local radio station. (Wish I'd known that. I was doing talk radio at the time. Would've loved to interview him.)
