'Blue Rita' aka 'Das Frauenhaus' (1977) – Jesús Franco.

Spain's premier perpetrator of permissively pulchritudinous peep-show perfidy unleashes yet another colourfully unexpurgated leer into the sublimely sinister, sinfully subversive sensual bacchanalia of the persuasively perky, delightfully depraved Blue Rita (Martine Fléty), and her scintillatingly perverse, serially sapphic, crank-yankingly lurid yen for malefic male bondage shenanigans, along with a terminally twisted, pant-wetting peccadillo for crudely administered, coitus-enhancing, limbic region-riling chemicals to insidiously inflame the increasingly demonic desires of the sensationally sadistic Rita's cruelly caged, lustfully-enraged male concubines!!! That most inventive Iberian instigator of psychedelically-inspired perversity is at his libido-igniting B-Movie breast with his Bourgeois sensibility baiting, bellicosely bonkers Blue movie boff-fest 'Das Frauenhaus' - why remain so boringly blue, when you can be 'Blue Rita'!
