Career
Born David Poole Fronabarger in Big Spring, Texas, O'Brien started his film career in bit parts before gradually winning larger roles, mostly in B pictures. O'Brien became familiar to movie audiences in the 1940s as the hero of the famous MGM comedy short film series Pete Smith Specialties narrated by Pete Smith. O'Brien wrote and directed many of these subjects under the name David Barclay.
O'Brien also had a small dancing part with Bebe Daniels in the Busby Berkeley musical 42nd Street (1933). He also appeared in many low-budget Westerns, often billed as "Tex" O'Brien, alluding to his home state. He appeared in Queen of the Yukon (1940) as Bob Adams.
In 1940, he appeared in The Devil Bat as part of a comedy team with Donald Kerr. They also appeared together in Son of the Navy (1940) and The Man Who Walked Alone (1945). In 1942, O'Brien starred in the movie serial Captain Midnight, and had the lead role in the western Brand of the Devil in 1944.
One of his later roles was in the film musical version of Kiss Me, Kate (1953), a rare featured role for the actor in an 'A' list big-budget production. A very keen yachtsman and sailor, he died aged 57 of a heart attack aboard a 60-foot sloop named The White Cloud while competing in a yachting race off the California coast near Catalina Island.
