Continuity mistake: In the chess scene, at the end of the (overlong) montage of shots of pieces being smashed, the White Queen turns her attention to a Black Castle. The first stroke of her sword clearly goes through the structure of the castle, which disintegrates. We cut to various different angles and watch pieces of the destroyed castle flying all over the place. Cut back to the original angle, and we see the Queen attacking again, but the Castle is completely intact - only the figure from on top of it is missing. And it can't have been the second castle, since that's Hermione's position. (01:58:26)
