Barbarella

Jane Fonda's memorable, zero-gravity striptease during the opening credits of this 1968 Roger Vadim movie is the closest the film comes to a liberated marriage of wit and sex. Based on a French comic strip, the story concerns the adventures of a 41st-century woman, who pretty much gets it on with whomever asks. The sci-fi sets were pretty interesting at the time, though they look rather anachronistic now. Appreciated today mostly as a camp classic, the movie is actually more trying than anything else. --Tom Keogh
