If this fiesty brunette looks fierce, that's because she is. Allison Hayes eventually achieved infamy as the star of the cult classic Attack Of The 50-Foot Woman (1958), but prior to that super-sized role it was Hayes' performances as the amoral Erica Page in the 1956 western Gunslinger and a bloodthirsty witch in the time-travel flick The Undead that first caught America's roving eye.
