David Walton was an accomplished TV actor who was always working, yet rarely seemed to be cast on a show that lasted longer than a few episodes. Walton's first series regular role came in 2004 when he joined the cast of Fox's "Cracking Up." The show, however, was cancelled after six episodes. That same fate of early cancellation would befall the next five TV shows Walton appeared on, among them "Heist" (NBC 2006) and "Perfect Couples" (NBC 2010-11), before an undeterred Walton landed the lead role on the sitcom "About a Boy" (NBC 2014-15). He may have encountered numerous professional disappointments throughout his career, but time and time again David Walton proved his uncanny ability to forget about the past, move on, and secure new TV work.
