When Harvey Dent has his bandages removed after the accident in part one, both of his arms are normal. Yet, in part two his left arm is blue and scaly like his face.
Harvey has his arms crossed as Thorn is trying to get under his skin, and the piece of cloth visible in the space between two of his fingers is colored like his skin. It should be blue, like the rest of his clothes.
When Thorne throws the newspaper in the fire, a few frames of animation are briefly seen that say CUT THESE FRAMS [sic]
When Rupert Thorn is reading Harvey Dent's psychological profile, there are no words written on the paper.
