So, I'm watching the film "Ed Wood", which is pretty entertaining. I happen to be near my computer, so I go online and IMDB Bela Lugosi. Under the subject of "Trivia", I find this little gem:

He performed in live-action reference footage for the "Night on Bald Mountain" sequence of Walt Disney's Fantasia (1940). He was, of course, the demon.
You know, I can totally see that. Especially when he picks up the little dancing demons and smiles at them. That's totally Lugosi's smile.

Anyway, I just thought I'd post that. If anyone wants to add some other trivia, go right ahead!
