But he's Scottish!
Those are some big names! Butler explains his character:
"I play the most perverse, disturbing, disgusting, foul-mouthed leprechaun you could ever imagine. I've been kidnapped by Johnny [Knoxville] and Seann [William Scott] so they can get their pot of gold. But they don't quite realize what they've bargained for."
Sounds like some solid casting choices to us!
