1968's Night of the Living Dead launched the career of director George Romero and reinvented the zombie mythos. It took a while to catch on but when it did? There was no stopping the film.
The Crimson Cult (1968) aka "Curse of the Crimson Altar" on 8mm
The cinematic equivalent of cotton candy, the visually stunning Barbarella (1968) stars a wide-eyed Jane Fonda as a futuristic astronaut who loses her clothes in the line of duty a lot. I suppose it could be called a "camp classic" in that it's filled with eye-candy and the dialogue (by over a half-dozen different writers) is painfully stupid.
AKA "Doctor Death: Seeker of Souls" 1973 tells the tale of a 1,000 year-old magician who, periodically, has to transfer his aging soul into a young, healthy body.
