Jensen Ackles is Batman
I am convinced that were the writers of Smallville actually allowed to use the Batman character that Jensen Ackles would have played young Bruce Wayne instead of the made up character Jason Teague.
This would have been awesome because Jensen would have been an awesome young Bruce Wayne, but it would probably mean the character would have stayed with the show all the way to season 10, which means Jensen wouldn't have been able to play Dean Winchester. And I can't imagine anyone else playing Dean.
Though a very large part of me longs to go to an alternate universe were Jensen is playing young Bruce Wayne.
