I read recently that there's actually a sequel in the works. It's called The Woman In Black: Angel of Death and it's slated for release in 2015. It takes place at Eel Marsh House during World War II - some Londoners end up at the old house to escape the Blitz and run into the home of The Woman In Black. The first trailer was just released.
Did you see the movie? What did you think? Will you check out the sequel?
