Jon Hamm has been rumored for a major superhero role ever since he made his name as Don Draper in the first season of Mad Men. Over the years he's been a fan favorite bit of casting for Superman, actually played Mr Sinister in New Mutants before being cut from the film and has been repeatedly linked to The Batman. With the presumed departure of Affleck from the role that last bit of speculation has picked up steam lately and Hamm has at least one major cheerleader in his corner: director and comics fan extraordinaire Kevin Smith.
