I vaguely remember seeing a commercial for this movie a long time ago. I don’t remember much, but what I do remember was that there was a woman who was chained, either by the neck or the ankle, I don’t recall, to a longish length of chain. I believe she was only wearing underwear, and I want to say that she was being held captive in a trailer home. I remember at one point she is walking outside of the home (the chain was pretty long as I recall) and someone from inside jerked her back.
I know it isn’t much to go on, but if anyone knows I really would like to see it.
Could you be thinking of Black Snake Moan with Christina Ricci and Samuel L. Jackson?
