The Black Sleep stars Basil Rathbone as a surgeon who uses the 'Black Sleep' drug to experiment on live subject in order to save his wife. Bela plays the bit part of Rathbone's butler, who was a test subject and is now mute because of it.
It always makes me sad to see this movie because of Bela. He was such a fine actor with a distinctive voice that having him play a tiny role of a mute seems like a waste of his talent. Don't get me wrong, he does a great job with the little he's given. Still, it's a sad statement about his career, and of how badly Hollywood treated him.
