Matt Walsh auditioned for the role of Dwight but lost out to Rainn Wilson. Walsh has shown he can play similar roles in the past and he would have been an interesting choice here. He’s been largely confined to cable series and bit parts in big movies in recent years (The Hangover, Role Models), but starring in The Office would have certainly bolstered his fame. All four of The Office's main actors were able to parlay their TV stardom into major movie roles, and Walsh would have had opportunities to do the same. If he’d found success in this high-profile role, Walsh's fanbase would have carried over to the UCB theaters, which he co-founded, drawing even larger crowds to the highly-popular comedy hubs.
