Continuity mistake: After cutting Elizabeth's hand, Barbossa says, "Waste not," and there's a wide back shot of the two of them, Barbossa is holding the knife in his right hand, and the edge of the blade does not have blood on it. In the very next shot, a close-up of the medallion falling from Elizabeth's hand, the edge of the blade now has blood on it. In a later shot when Barbossa looks at the blade, there is blood on both sides. (01:12:15)
