Night of the Living Dead 3D (2006)

Continuity mistake: Right after Karen bites her father's neck, a bandage is placed on it. Immediately after this, Gerald fights his way to the house and they let him in. For several shots, there is no bandage, wound, or even blood on the father's neck while Gerald is explaining what's been going on. Then suddenly a close-up of the father shows that the bandage has re-appeared without anyone putting it there.
