Continuity mistake: After escaping, while Jack is swinging quickly about on the rope, in the first wide shot, he hangs low on the rope and the excess rope reaches his knees. When Jack yells, "Whoa!" he is higher on the rope and yet the excess rope still just reaches his knees. Then when Norrington shouts, "Open fire!" still higher on the rope, the excess rope is now way below his feet. (00:19:50)
