I was just watching "Adventures of Superman" (in between Gilligan's Island) and was surprised to see Russell Johnson in "The Runaway Robot" circa 1951. Another coincidence was one of the characters was called Hinkle. Pretty close to Hinkley. It was interesting seeing him play a baddie.

I have never seen it but it sounds cool

here are some pictures of him on it http://www.sitcomsonline.com/boards/showthread.php?t=154536&highlight=Request+Superman+DVD
