"When I came out here, LA was nothing. Back East, I was a gangster. Out here, I was a God." That's Sean Penn doing his best Al Pacino impression. He's wearing a hat.

"It doesn't seem right that he should have so much while others have so little." That's Ryan Gosling as a suave, gangster-hunting good guy. He's also wearing a hat.

Put them together and whaddayagot? A LOT of hat-wearing. But that's not all. Imagine Nick Nolte, Josh Brolin and loads of other guys ALL WEARING HATS. Now imagine them being given really cool things to say like "You can't shoot me, you're a cop". Now imagine with them guns. And suits. And really cool music.

Now stop imagining and watch the trailer for Ruben Zombieland Fleischer's Gangster Squad (full HD is over at Apple) - it's conclusive proof once and for all that even if your film looks all over the place, Ryan Gosling in a hat makes everything better. (Warning: Trailer features perhaps the coolest final 10 seconds of a video ever.)
