Edmond Bateman

Edmond Bateman, played by Boris Karloff, is a character in the 1935 film The Raven.

Bateman is a serial killer who suffers from bouts of rage because of his appearance. He attempts to appeal to Dr. Richard Vollin to help him, thinking if his appearance was corrected, he would be able to reform.

Instead Vollin turns Bateman into a monster promising only to help him if Bateman first does his bidding.
