Not much is known about this project except that it was seriously considered after the semi-success of the 1958 film staring the voluptuous B-movie cult figure Allison Hayes as Nancy Fowler Archer, an heiress who grows to such a height after an encounter with a alien giant and his craft while driving through the desert.

Special thanks to Eric Hurd, a fellow giant monster fanatic and 'historian' who first brought the info to my attention from an issue of Scary Monster Magazine which makes mention of the unmade sequel.
