Angels with Dirty Faces (1938)

Rocky Sullivan and Jerry Connolly were tough kids who grew up together in the toughest part of New York --- Hell's Kitchen. Early on, Rocky gets sent to reform school, where he learns how to be a first class criminal. Jerry, who had escaped from the law, goes straight and becomes a priest. As adults, they reunite in the old neighborhood: Jerry works with the kids who, like he and Rocky, could end up on either side of the law. Rocky has returned looking for a safe place to stay till he can get back into his old racketeering organization -- something that his old partner isn't anxious to have happen. Lots of rapid fire wisecracks, roughhousing and gunfire ensues.
