I love how at the beginning of the interrogation the joker is in complete darkness. Nolan directed it so you can only see his face. It makes you wonder if something or someone is behind him. The way the joker speaks with perfect grammar is also great because it shows that he is a very intelligent and capable man. This is clearly the jokers scene. What I don't like about this scene is that the joker seems to not be hurt at all after being thrown all over the room. He shakes off a brutal beating.
