"Come out and take it, you yellow-bellied rat," James Cagney snarls after cornering the hood that killed his younger brother. The line, with a bit of poetic license, has been quoted ever since and has become sort of a litmus test for any impersonator worth his salt. Cagney, needless to say, is at the top of his form in Taxi, an otherwise oddball gangster thriller that sometimes veers dangerously into parody. Not that Cagney is the only tough guy around; there is also George Raft, who, after defeating Cagney and partner Loretta Young in a dance contest, triumphantly sneers, "How do you like that, wise guy!" After which, Cagney simply slugs him. Even the otherwise so ladylike Young gets in on the act. Warned that "for two cents I'd knock the ears off you," Young retorts, "For less than that I'd slap your face!" Taxi is simply that kind of movie.
