No question. It's kinda his thing right? He gets kicked in the pills, smacked in the face, run over by bulls for a living. There's nothing about this role that doesn't scream Knoxville to me.

Im not a huge Stooge person. Is the "lead role" the guy with a moderate brain? or is he the clueless one?

Really, I have no idea why people get so hung up on looks when in comes to reimagining/casting parts. The looks aren't that important at all really. They're a nice perk to get right, but really far down on the priority list for getting it right. First and foremost you just want somebody that can get the personality right and can properly embody the character and his/her personality.

For that, Knoxville is perfect.

And the below picture says he can pull the look off well enough to satisfy me.

Why does that matter though? In what possible way does that effect his ability to play the part? Elijah Wood is like 5'6'', didn't stop him from playing a 3ft character sufficiently. Sherlock Holmes is written to be a good bit over 6ft tall. Didn't stop the 5'8" Downey from playing him well.

I'm sure the list can go on and on. The point: No. He's not the same height. But what does that have to do with anything? That has no bearing on one's ability to play the role and embody a character. He can get close enough to the look (as evidenced in the picture) to pull off that classic Moe look, so you can pretty much instantly tell who he's supposed to be (especially in context). People get way too caught up on physical appearance and matches. Especially with the absolutely trivial stuff like height (or bra size).
