Robert Downey Jr is Too Dumb to Understand The Dark Knight. His Words… Robert Downey Jr was known for some things, then everyone forgot who he was, then they remembered again. And now that the people of the world once again recognise Robert Downey Jr in the street - and now that he's likely off the smack and charlie - people are more likely to listen to him. So it comes as a nice big pile of fun when the man gets all ranty, decides he disagrees with just about everyone in the world and that he hates The Dark Knight, because it makes him feel 'dumb'. For once we don't have to add much to that - it's simply what he said in an interview with Movie Hole.
