Okay, so. Edward G. Robinson. If you recognize his name at all, you probably think of Bugs Bunny suddenly having big lips and saying "Listen here, you mugs! Mnnnyaaahhh, see! Mnnnnyaaahhh!" Police Chief Wiggum sounds a bit like him. I'm a bit ahead of the game because I've seen him in a couple of movies, like Double Indemnity. But I'd never seen him in the iconic gangster roles that made him worthy of Bugs Bunny. Hence Little Caesar, which played as a double feature with Public Enemy, in which James Cagney made being a sociopathic gangster look awesome.
Well, it turns out that Edward G. Robinson is pretty cool. He's more of a sociopath than Cagney's character, to the point where the other hardened gangsters are a little creeped out by how willing he is to whip out his gat and start gunning down anyone in his way. He's not quite as magnetic as Cagney, but that's just because he looks, well, weird. Really weird.
The other reason I wanted to see this movie was because it ends with "Mother of mercy, is this the end of Rico?" I've heard that line a lot and always thought it sounded really odd and forced. In context, it turns out that it sounds just as weird. Huh.
