Russell Crowe (52)
One of the biggest asses in Hollywood, Russell Crowe, showed has shown his own in five different flicks, but never so memorable as 1993's Hammers Over the Anvil. Here you can catch Russell riding a horse nude to ford the river, 'cause, why the hell not! See the clip below, and check out some stills in the gallery! Maybe one day we'll see if he's one of the biggest assholes in the biz as well.
