As any cinema fan knows, it ain't a film if Sam Rockwell's not in it. And Sam Rockwell's not in it unless he's dancing. Contractually obliged to tap his toes and/or strut his funk whenever a camera comes close, his stellar moves are as versatile as his acting.

He's such hot stuff that in Conviction, he gets arrested for dancing in public. And taking his clothes off. And supposedly killing someone.

But no matter what The Man says, I say his slick dance-floor moves deserve to be celebrated. So if you fancy a stint behind bars (and have Hilary Swank to hand to spend her whole life bailing you out), here's a look back at his best dances (they're all the same) to work out how exactly you Do The Rockwell.

Charlie's Angels (2000)

The one that started it all off. Eric Knox's sexy smooth moves put the sole back into shoes. Or something.

Confessions of a Dangerous Mind (2002)

I'm a massive fan of this film, even though most people seem to have never seen it. Ever wondered why Sam Rockwell was so good at being Chuck Barris on screen? It's because he can do THIS off screen. Check them skillz, yo.

Iron Man 2 (2010)

Yeah, everyone saw this one - Justin Hammer was hard not to miss, being one of the only good things about the sequel - and suddenly everyone loved Sam Rockwell's dancing. Well HANDS OFF. I SAW HIM FIRST. (Insert your own Hammer Time joke here.)

Moon (2009)

Oh, what's that? You thought Moon was a serious piece of sci-fi with an intelligent theme and lots of depth? Well, you're right. It's awesome. But it also had Sam Rockwell dancing to Walkin' on Sunshine. In front of himself. Now THAT'S deep, man. Or it's a serious dance addiction. Whatever.

The Hitchhiker's Guide to the Galaxy (2005)

This just about qualifies as dancing, but it's a perfect example of how to deploy the Pelvic Thrust to maximum effect. Vote Zaphod.
