The astounding thing about this is that it comes as a total surprise. It’s nearly an X-rated peek at her privates in the very closing moments of the film. (This version has been brightened, but not faked.)
(She did say earlier in the film, “If you save the world we can do it in the asshole,” but I was expecting the payoff to occur off-camera.)
Screw the lousy sled, now that’s a rosebud!
Keep your pensive, ambiguous 70s-movie conclusions, THIS is how you end a movie!
