The Haunting is a classic and I happen to be a fan of Jan De Bont's '99 remake. But the remake's story around Eleanor was overkill. Nothing close to the original which used little special effects to make the haunting scarier than it's remake. It's a classic amongst horror film fanatics.
Changing the subject a little, I recently heard Guillermo's film (if greenlit) would be a PG-13 rating. Would this be the second release under Walt Disney Pictures with that rating?
