Most of the gals in Jean Rollin's films spend the running time in a state of undress. He seems to have gone through every Euro chick available that's willing to doff her togs, the gorgeous Bridgette Lahaie included. The Horror Channel's midnight slot seems to be taken up with them. And no bad thing, BTW!
EMANUELLE IN AMERICA though has the most nudity, to say the least, in a horror film IMO. More Euro sleaze than Euro horror, it does feature some quite astounding effects work by Gianetto De Rossi, he of Fulci zombie infamy as well as the recent HAUTE TENSION.
I think that the 1967 film zombies is probaly the stupidest horror movie on the world first the woman goes skinny dipping in the middle of the ocean then is attacked by a zombie so a shark then attacks it so the woman goes home and takes shower (nude) and show a splinter going through her eye then i decided the movie was so stupid i sent it back to Netflix
