Barbarella (1968)

 Barbarella (1968)

If you're looking for a cult classic, they don't come much stranger than sexed-up and super-silly Barbarella, the peculiar tale of an intergalactic secret agent (Jane Fonda) sent to a rebel planet to find a mad scientist named Duran Duran (Milo O'Shea.) Directed by Fonda's then-husband Roger Vadim, the film is less concerned with creating a coherent storyline than it is in finding inventive ways to strip Fonda of her already skimpy outfits.

True enough, Barbarella was probably much more entertaining back in the days LSD, and indeed one might read the entire thing as an acid trip time machine. No one in the cast takes the film very seriously, and neither should you...(IMDB Gary F. Taylor)
