Taxi!

James Cagney plays a cab driver whose quick temper causes problems in his relationship with Loretta Young, who hates violence. When his kid brother is killed, Cagney is out for vengeance. But getting it may cost him the woman he loves.

Jimmy's great. He makes a sometimes unlikable character relatable. Loretta is very pretty and endearing. George E. Stone, Guy Kibbee, Leila Bennett, and David Landau are part of the nice cast. George Raft has a bit part where he gets socked out by Cagney. Opening scene where Cagney speaks Yiddish is a classic. This is the movie where Cagney yells at his brother's killer "Come out and take it, you dirty yellow-bellied rat, or I'll give it to you through the door!" This would later be misquoted as "You dirty rat, you killed my brother!" and would become a staple of Cagney impressions.
