Out of all of these choices I think the best has to be Scott Caan. However, there's something uniquely rural Americana looking about Matt...Scott Caan doesn't quite capture that, he's too urban or something...I think he's the closest bet in terms of build tho, but acting wise I don't think he'd play a Matt akin to Matt. He's too smarmy in his delivery.
Perhaps William Lee Scott who is the same age as Matt btw, same overall look except he'd need to gain some weight coudl fit the bill. His pitch is higher tho..
