the story of O (1975)

aka Histoire d'O.
"Submit."
Rene (Udo Kier) takes O (Corinne Cléry) to an isolated manor and submits her to a variety of sexual perversions to make her submit to him, sharing O with several men before he gives O to his older step-brother (Anthony Steel).
Well shot, but uninvolving and slow story.

gwendoline (1984)

aka The Perils of Gwendoline in the Land of the Yik Yak.
"Feel like dying?"
Gwendoline (Tawny Kitaen) hooks up with Beth (Zabou Breitman), and adventurer Willard (Brent Huff), to try and find her father. He was last seen searching for a rare butterfly in the Land of the Yik Yak, so that's where they go...
Good looking 1930's style serial adventure, which is a dumber version of Indiana Jones, with added nudity.
