Bunny Lake Is Missing (1965)
Though it's not may a horror film but the beautiful black & white photography and stunning camera works from the director Otto Preminger gave a haunting tone to this simple but effective psychological mystery-thriller. And personally I always very much fond of this kinda Hitchcockian tales. Nonetheless the film has a great cast including Laurence Olivier (a gem of a performance as the police inspector), Carol Lynley and Keir Dullea (they really looked like brother & sister!).

The Fearless Vampire Killers aka Dance of the Vampires (1967)
The best vampire comedy ever made; almost without a bloodshed in the film. What a stunning beauty Tate was!
But it's really sad for anyone to watch her on screen with Polanski after knowing about the untimely & shocking death of her by the Manson family.
