This movie is a cinematic collage of gangster clichés. The writing is grade z and the plot and story are constructed without care or logic. It a messy pastiche of stereotypical gangsters (think of Bugs Bunny cartoons) and silly supporting characters (the lady doctor and the writer). There are much better Bogart films out there. In fact, Bogart looks like he slept through this performance. He puts very little effort into this character. I think the directorial advice he received was something like "He's a bad guy. Act bad". This guy is the era's equivalent of Darth Vader; obvious, evil and the anti-hero. Don't waste your time with this one.
