When Jake is yelling at Philip in the interrogation room, saying that he will spend the rest of his life in prison, everyone who loves him will forget about him, and a bear will have sex with his head, in the shots focusing on Jake, Jake is emphatically pointing with his left hand, but in the shots focused on Philip, it suddenly switches to his right hand.
