Peter S. Fischer won an Edgar Allan Poe award for Best Television Episode (Murder, She Wrote, "Deadly Lady") in 1985.
Peter S. Fischer: (Describing working with Angela Lansbury on Murder, She Wrote) It's hard for Angela because she can do 90 percent more than we ask. But the key to success in a series is a nice predictable character doing things in a predictable way. Actors who are bigger than the medium don't succeed. Angela can effortlessly project a warm and lovable human being.
