When the boys get to the room, Mr. Potato Head is under the crib with his left ear back in place; he found it off screen. It's appropriate for him to look for any missing pieces of his before rushing back into place.

A close-up of Irons' hands, however, reveals that the zip-tie only wraps around his right wrist while crossing about mid-way on his left thumb, meaning that he could easily remove his left hand from the restraint with very little effort. Arresting police officers would never make this mistake in real life.
Character mistake: When the Rohirrim are preparing for the Helm's Deep battle, a man is shown sharpening a sword on a grindstone.
