The Shadow Within (2007)

A nine-year-old boy becomes a conduit for evil spirits in the supernatural thriller The Shadow Within (2007). After his twin dies at birth, Marie Dumont (Hayley J Williams), too busy mourning her dead child to love her living one, neglects her son Maurice (Laurence Belcher). At the urging of her psychic pal Madame Armand (Bonny Ambrose), Marie talks Maurice into becoming a conduit for communicating with his dead brother. Finding he has a gift for talking to spirits, the grieving mothers of their plague-ridden village start lining up to use Maurice’s talents. But evil follows Maurice back from the other side, and soon his twin brother wants his family to join him in death. Hayley J Williams is one hot mama when she strips completely nude swimming in a strange, womblike pool 33 seconds in. She reappears in her birthday suit 1 hour, 24 minutes in, but this time she’s also being strangled by a ghostly umbilical cord. Good thing we get furtastic flashes of her trim as she flails around in the water. The Shadow Within will put a devil within your pants!
