I was listening to commentary that they added the mother's picture because later on they would have Barb hallucinating that a zombie was her. It seems interesting in theory, but what significance would it hold? I know the original had Johnny coming back making her suffer a mental break down and shock value. Since they changed Barb, why not have their mother really rise and have her deal with it?

Would they kill their zombie mother?
