Better still, with its high drama in every scene and the sensibility-laden dark pasts of its characters Attack of the 50 Foot Woman (1958) has a film noir sense to it, mildly reminiscent of some of the mightier classics of the form as recently best exemplified in Kiss Me Deadly (1955).
In a twist reminiscent of The Incredible Shrinking Man, the shrink n grow trope of the era as super-excited by the atomic atoms in the airbflips the script by featuring a character zapped with a growth ray set to "Grow" instead of "Shrink." However, this newfound size comes with enormous challenges for the protagonists to overcome.
