Curse of the Black Widow [1977] [DVD]

After the success of his his Kolchak movies and series, Dan Curtis tried to spring on us another nearly likeable character in the form of actor Anthony Francioso. The similiarities are obvious as several men are being found butchered with large amounts of black widow venom in their bodies. The incredulous solution is that their must be a giant spider running loose, and then it turns out the giant spider is really a woman.
