Don Keefer has spent most of a working life as an American actor who has spent far more time working than being talked about. 'Butch Cassidy and the Sundance Kid' is close behind in visibility. The first credits arrived long before the title most people know. Drama keeps coming back on the credit list. Television and film have both stayed in regular use across the career. 'Liar Liar' is the title most people reach for first, with Beggar at Courthouse at the center of it.
