Attack of the 50 Foot Woman
The founding text. Nancy Archer grows after an encounter with an alien and goes looking for her cheating husband. Crude even by 1958 standards, and none of that has ever mattered - the poster alone did more for this fetish than any film since.Worth watching: The final act, once she is loose in town.
