The live-action version of “Fallen Angel Ryu,” Operation 11 from the Cool Devices adult anime, starring Britney Spears and staying SLAVISHLY true to the original hentai. McG directing, of course (he’s not a good mainstream director, but I sense a great pornographer in there somewhere.)
Fallen Angel Ryu deals with a “virgin idol singer” whose father manages biz badly and then falls deadly ill. Her contract is bought out by evil corporate white slavers who force her career into an entirely new direction, forcing her by degrees to become less and less of a virgin idol sort of person until she winds up about the opposite.
