Turned down the role of the monster because he felt himself too well trained an actor.

Davis almost was cast as Elizabeth in the movie, but Director James Whale was more impressed with Mae Clarke and chose her instead

Was offered the role of Dr. Henry Frankenstein.

"Dracula" was a huge success and Universal was anxious to follow up with "Frankenstein" but Lugosi wanted to play the Doctor and he was offered the monster role. He turned it down due to "lack of dialogue" and the part was given to the relatively unknown Boris Karloff.
