Before I say anything. No, I don’t have a problem with castings like Jon Hamm as Batman. BUT, y’all really need to stop adding actors like Armie Hammer as Batman because Armie is a fucked up person who shouldn’t be used at all. As for official castings. Using things like Bryan Cranston as Jim Gordon and Edward Norton as Hulk to stories where they’re either A. Too old. Or B. Don’t fit the character the story has.
Official/or basic castings
What’s wrong with Cranston as Jim Gordon?
It’s already official and it’s heavily overused. That and there are other characters for Bryan other than Gordon that Bryan can play
People have their preferences. Bryan Cranston as Gordon isn't official, so i don't see any issue with it. Meanwhile casting people who're already playing the character when it's specified not to cast them is a legitimate problem.
He voiced him in Batman: Year One
BUT, with the rest of what you said is the reason why I’m complaining about it. Like in any Batman fancast that involves him being younger they always cast Pattinson
I still don't see a problem, when it's a live-action story. I'm sorry, but i don't find a problem with that.
