BOWIE!
He should play Bowie! I bet he can pull it off too. Maybe a couple of years down the line but I bet he'd be able to play him from beginning to end seeing as how he still looks like a kid but is also a very versatile actor.
Goodness knows why the hell the chose him to play Sir Paul. Doesn't look a bit like him. Guess cuz he's just too pretty...kinda like Paul was.
