Okay, I know this might be a bit vague, but somebody asked me if I knew what this movie might be, and I really have no idea. It's a black and white featuring a castle. Apparently a lady is disfigured by falling into a pit of lye. I know that the House on Haunted Hill has a pit of acid and that it is not the movie they are looking for. She may have been locked away in the castle. This is one of those, 'I watched it as a kid and can't remember the movie, but remember details' type of thing. If anyone has a clue, feel free to share.
