Continuity mistake: During the giant siege on the English castle, the giants use grappling hooks to pull the drawbridge open as the human defenders inside struggle to pull the drawbridge closed with an enormous hand-winch. The giants overpower the humans, and the huge hand-winch is actually torn loose of its moorings and tumbles away, useless. The humans then scramble to use "scorpion" tow lines to close the drawbridge. As the order is given to man the tow lines, the camera briefly cuts to the drawbridge entrance, where we again see the enormous hand-winch, still on its moorings, quite intact and fully functional.
Suggested correction: There are two winches for the drawbridge, one for each side of the bridge- the one you see intact is the other winch.
