Hmmm........ I was trying to think who could pull off the roles of these three classic characters. Just not a lot of folks out there that really fit the bill for these guys.
Jeff Daniels would be a pretty good choice for Curly. I can see him with a buzz cut and portraying the guy pretty well.
Mike Myers as Moe. Long as he can do the role without a scottish accent.
Andy Dick or Chris Elliot as Larry. Elliot would probably be the best pick.
