Chicago Reader review:
A scientist (Grant Williams) exposed to radiation grows smaller and smaller in this faithful 1957 adaptation of a bad Richard Matheson novel; it's a lot more interesting than its source, thanks to the special effects and Jack Arnold's taut, no-nonsense direction. The surreal intensity of outsize objects that loom as the hero shrinks is handled effectively, and the mystical happy ending is a better payoff than one would expect of the genre.
Spoiler alert: here and above is the closing monologue.
