Wilczyca (1983)

Hell hath no fury like a woman scorned in the Polish werewolf flick Wilczyca (1983) Maryna (Iwona Bielska) hates her unfaithful husband Kacper (Krzysztof Jasinski), and puts a curse upon him with her dying breath. This curse comes back to lycanthropically haunt not only Kacper, who now turns into a wolf at every full moon, but also his younger lover Julia (also played by Bielska), who is afflicted with the same condition. Iwona is howlingly hot when she shows us just the quickest hint of skin in the tub, but sadly we don't get a good view of her full moon.
