The Boogie Man Will Get You is a 1942 American comedy horror film directed by Lew Landers and starring Boris Karloff and Peter Lorre. It was the final film Karloff made under his contract with Columbia Pictures, and it was filmed in the wake of his success in the 1941 Broadway production Arsenic and Old Lace. As he had done several times previously, Karloff played the part of a "mad scientist", Professor Billings, who is using the basement of his inn to conduct experiments using electricity to create a race of superhumans. The inn is bought by a new owner, who is initially unaware of the work Billings is conducting.
