Newman, who retired from acting in May 2007, has had a varied and acclaimed career, including turns in "Butch Cassidy and the Sundance Kid" with Robert Redford, and The Color of Money with Tom Cruise, for which he won the Best Actor Oscar.
Newman also heads several charitable organizations, including the Newman's Own brand of foods.
