Edmond O'Brien puts the "action" in the "action-packed expense account" of Yours Truly, Johnny Dollar. The Academy Award-winning actor starred as the freelance insurance investigator from 1950 until 1952. O'Brien's tough style – honed in film noir performances – brought a hard edge to Dollar, a character that had been decidedly lighter in the hands of Charles Russell. His run as Johnny Dollar has cemented Edmond O'Brien as a fan favorite of the many actors to play the gumshoe. We'll hear O'Brien as Dollar in "The Caligio Diamond Matter" (originally aired on CBS on June 8, 1950) and "The Calgary Matter" (originally aired on CBS on July 13, 1950).
