There hasn’t been any good Dark Knight Rises speculation going on for a while, so I’m going to resurrect one that hasn’t been seen in about a year— Joseph Gordon Levitt could be playing the Joker, not some beat cop and Christopher Nolan used that as a red herring.
First, just look at that comparison photo. Sure, Ledger had a slightly bigger build than Levitt does, but in the slightly oversized Joker costume and the way he hunched over, his body shape was completely lost. The important part here is the face. Very, very similar.
Here’s an artistic interpretation I dug up for further comparison:
Second… JGL was known to be in talks with Nolan for a “major role” for a while, and had worked with Nolan before, and after months of speculation on who Levitt would play— many people were speculating the Riddler or Robin— he gets cast as a cop? Nooooo.
The character Levitt is listed as playing is “John Blake”, but if you take the first two and last two letters from that name, you get “Joke”. Hmmmm?
Despite some leaks, the last fifteen minutes of the film are crucial. So crucial, so secret, that only Nolan and a couple actors directly involved even had access to those script pages until right before shooting that final sequence. Again, many people have speculated that Levitt might end up playing Robin, and that this last sequence might be a lead-in to a Robin/Nightwing movie. I think that would be pretty cool, but I tend to believe Nolan at this point when he says that there is no place for Robin in his Batman movies, and there would have to be a lot more lead up than the last 15 minutes (I suppose) to introduce Robin.
But the Joker? He’s had his own movie, he doesn’t need a lead-in. All he needs to do is show up.
