'Mr. Belvedere' Loosely based on a novel that spawned some movies in the late 1940s and early '50s, "Mr. Belvedere" followed the weekly exploits of Lynn Belvedere (Christopher Hewitt), a world-travelling Brit who takes a job as a housekeeper for a Pittsburgh couple (ex-baseball player Bob Uecker and Ilene Graff) and their family, with plans to write a book about his experiences in middle America. A cornerstone of the ABC lineup, "Mr. Belvedere" ran for six seasons until its cancellation in 1990.
