I was hoping she would get undressed at some point.
I was dissappointed.

I, too, have seen this picture on the back of the Cydonia DVD release of Night Of The Zombies. My guess is it's a publicity shot that they shot on the set when they made that scene. Because there is no print that I've ever seen that shows the zombie dragging Josie away as it shows in the photo. I've seen the Vestron, Anchor Bay, and Cydonia releases and the scene is all the same.
BTW, I don't think that zombie is her father. By father, I believe she meant a priest.
