Glenn Manning....poor guy. Just wanted to save a guy in a plane crash and gets a face full of a plutonium blast. Oh, and plutonium has the effect of generating growth and it's madcap frenzy from Bert I Gordon.

Oops, watch that heart Glenn!

Believe it or not, in some circles (although not the ones I run in!) this film is considered a fairly decent Cold War parable...except that nobody can excuse the special effects. "It's the Amazing Colossal Double-Exposed Man!"

What drives me nuts about the movie is the endless stream of what The Worst Movies of All Time aptly describes as 'sci-fi simple-speak'. Basically, any time a scientist utters a word of more than one syllable, he must backtrack, oh-so-solemnly: 'His cells are growing at an accelerated - or speeded-up - rate', etc.
Nothing like being patronized by a schlocky B-movie...unless it's being patronized by a schlocky B-movie that insists that the human heart is made up of one cell!

Meanwhile: Love the 'Yep, we're calling from this entirely different helicopter, over' riffs. Also the 'seaweed' gags in the opening hospital scenes. (What is that stuff, anyway?)

I DON'T WANT TO GROW ANYMORE!!!

Great line:
"Poor bastard's screams were choked out with a mouthful of his own blood."

This the one where the guy is turned into a giant cyclops?

You're thinking of another Bert I. Gordon movie entitled (appropriately enough) The Cyclops.

Got it.
