While he is billed sixth, I think the real star of this picture was young Stanley Clements as 'Detroit' Harry! Clements' character was a hilariously terrible little juvenile delinquent and based on this worldy-wise and smart-mouthed character, I can understand why Monogram Studios decided to use him for a replacement when Loe Gorcey left the Bowery Boys late in their run. The series was nearly dead...but Clements did as good a job as he could as a guy much like Gorcey's character. I say watch the film for him alone...though overall it's a fun little gangster comedy.
Cesar Romero is Shep...a gangland boss who is very elegant and nice. How nice? It turns out he simply doesn't have the heart to kill his enemies and he keeps them all in a small jail he's had built in his basement! If his rival, Willie (Sheldon Leonard) finds out he's just a softy down deep, Shep will be pushing up the daisies. But, he might anyway when Willie decides to court Shep's fiancé! What comes of all this? See the film.
The script is funny and clever and the characters memorable. It's among Romero's better films and a nice little sleeper comedy anyone could enjoy.
