Are you sure this is the same movie?
 

Has anyone seen a film a while ago and then decide to watch it again only to wonder if its' the same film?

eg I saw the original The Hills Have Eyes back in the 80's and when it came on dvd a couple of years ago I watched it, but i can't remember half of the things that are in it. I know I've seen it because 1. I remember the original trailer at the cinema and 2. it was around the "Video nasties" era and 3. I saw it alongside The Hills Have Eyes 2, which I seem to remember involves some of the survivors of the first one including the dogs!

I also remember I Spit On Your Grave to be a lot worse but maybe old age is playing tricks with me.
