A Spin on Early Radiation Paranoia…Love That Bomb or at Least the Isotopes
28 December 2014 | by (United States) – See all my reviews

Odd Little B-Movie (clocks in at less than an hour) from Low-Budget Wunderkind Edward Cahn. There are Enough Bizarre Scenes and the Combination of Post Nuclear Radiation Experiments on Convicts & Gangsters is a Guilty Treat.

Not Enough Time or Money to Make the Thing Much More than it is, and that is an Entertaining, Good Looking Programmer that was Actually Quite Early on the Wave of Paranoia About the Bomb's After Effects.

It Tries to Spin the Concern Into a Helper of Mankind and that Radiation and the Nuclear Age Could Be a Good Thing. In Reality the Jury was Out and Truth be Told They didn't have a Clue.

The Scene that is at the Nucleus, a Murder, Post Radiation Treatment, Makes Robert Shayne Look Like a Bug-Eyed Maniacal Monster and is an Artistic Touch that is Quite Scary. There are Some (Mad) Lab Sets with Goggled Patients, and Some Gangster Activity with a Twist or Two.

Overall, Definitely Worth a Watch for its Quirky Plot and the Director's Command of Low-Budgets with an Eye for Sets and Set-Ups.
