What a fun movie!
Edward G. Robinson plays a respected doctor who decides that the only way to truly understand criminal behavior for an academic study he is writing is to become a criminal himself. He joins a thieving ring run by Jo Keller (Claire Trevor, looking hotsy-totsy) and proceeds to both help the thieves with their crimes while at the same time studying them for the biological and psychological effects of their actions. Trouble arises when Jo's right-hand man, played by Humphrey Bogart, begins to feel like a third wheel, and blackmails Robinson when he discovers his true identity.
This film is a real treat. It's funny, creepy and suspenseful, all at the same time. Robinson begins to enjoy being a criminal, and his detached approach to crime makes him capable of committing murder without a second thought. Is he sane or insane? That's the question a jury must answer at the film's climax, and one the viewer still won't be able to answer after the movie's over.
Robinson, Trevor and Bogart have enough chemistry together to start a fire, and the three of them would team up again 10 years later for another terrific film, John Huston's "Key Largo." Anatole Litvak provides the fluid direction.
