Talking of Kim, her animated character of Holly Would in Cool World broke new ground, somewhat different to Jessica Rabbit. As for erotic films though its not really up there with the usual soft nude offerings, and those that do have pink bits in them, only particular scenes (or two ) could be classed as erotic, rather than the whole film - Basic Instinct, 91/2 Weeks, Betty Blue.
I would have to choose some of the 70s female vampire films, in particular Lifeforce, definitely has to be a film thats more tongue in cheek though, than trying to be serious.
