Great request. Lisa was the original Wednesday Addams in the black-and-white TV version of The Addams Family (“Why, thank you, Thing.”), and she did some excellent nudity in this film.
Unfortunately, the available sources are crap. I did find a DVD, but the quality is poor. It’s obviously just a VHS transfer. Such a shame! This could be a terrific nude scene if anyone could find a pristine print and transfer it to Blu-Ray. There’s even a brief “open coochie” shot when she climbs into the hot tub.
Alas, this is all we have now:
