"I retired five years ago and it hasn't worked out," Van Dyke, 81, jokes. The Diagnosis: Murder star recently appeared in an original TV movie for the Hallmark Channel, Murder 101: College Can Be Murder, which also featured his 55-year-old son, Barry. Van Dyke also appeared in last year's movie comedy Night at the Museum.
