Continuity mistake: When Abomination pins Hulk to the wall, and Hulk starts to push back, at first, when the camera view is level with their heads, Abomination's left hand is grabbing Hulk's right forearm. But when the camera view lowers to their abdominals, Hulk's right hand is grabbing Abomination's left forearm.
