"The Haunting", psychological horror film by Robert Wise (UK, In black and white with no special effects. Skip the remake crap and cuddle up with this one in the dark. Based on the Shirley Jackson novel.
Casper: First off, Bill Pullman. I could just leave it at that and this movie would still be awesome, but even without Bills greatness, Casper is still the sweetest movie. It makes me smile, rage slightly and cry every time.
