American actor Frank Wilcox had intended to follow his father's footsteps in the medical profession, but financial and personal circumstances dictated a redirection of goals. He joined the Resident Theater in Kansas City in the late '20s, spending several seasons in leading man roles. In 1934, Wilcox visited his father in California, and there he became involved with further stage work, first with his own acting troupe and then with the Pasadena Playhouse. Shortly afterward, Wilcox was signed to a contract at Warner Bros., where he spent the next few years in a wide range of character parts, often cast as crooked bankers, shifty attorneys, and that old standy, the Fellow Who Doesn't Get the Girl. Historian Leslie Haliwell has suggested that Wilcox often played multiple roles in these Warners films, though existing records don't bear this out. Frank Wilcox was still working into the 1960s; his most popular latter-day role was as Mr. Brewster, the charming banker who woos and wins Cousin Pearl Bodine (Bea Benaderet) during the inaugural 1962-1963 season of TV's The Beverly Hillbillies.
