After decades in the business, Frank Overton is the kind of actor with a body of work built one job at a time. Ask a viewer to place Frank Overton and the answer usually comes back 'To Kill a Mockingbird'. 'Fail Safe' counts among the more visible credits. The filmography reaches back well before the best-known title. More of the credits fall under drama than under anything else. 47 credits across 79 years is a rate most careers never reach.
