Donald Pleasance (who, according to imdb, has appeared in over two hundred movies), is probably best known as Dr. Loomis, psychiatrist trying to stop madman Michael Meyers in Halloween; Halloween II; Halloween IV: The Return of Michael Meyers; Halloween V: The Revenge of Michael Meyers; and Halloween: The Curse of Michael Meyers.
Pleasance also portrays the great cinematic Bond villain Ernst Stavro Blofeld (who has a fluffy white cat and lives in a hollowed out volcano!) in You Only Live Twice. Not the worst legacy to leave behind, if you ask me (Pleasance passed away in 1995).
I love character actors! Brad Dourif, Clancy Brown, Pleasance–I love them all–but Pleasance also had the distinguished nickname of “The Man with the Hypnotic Eye“.
But what do you think?
