Continuity mistake: When Eowyn and Merry run up to defend Theoden from the Witch-king, they stop right by the dead horse's tail, but when the shot cuts to front view, they're suddenly in front of the horse's feet.
Continuity mistake: During the troll boss fights in the Black Gate level, the trolls' weapons often change from rock wedges on sticks to rock wedges on chains.
