Revealing mistake: When Chazz summons Reborn Zombie in Defence Mode, the monster appears on the duel field, as well as the playing card beneath it, positioned at a horizontal angle, for it to stand on.

Other mistake: When Jaden and Syrus enter their dorm room, the curtains are closed, but this doesn't affect the lighting at all.
