Bad movie but historically impotent in at least one way
It is, as far as I know, the only PG-rated fetish-film ever made. (I'm not counting the sequel because I think that's a PG-13-rated fetish-movie)
Gwendoline might as well have been PG-13, since apart from nudity and the torture room scene, nothing really happens.
Fortunately, Ah keep mah feathers numbered for just such an emergency!
