I had seen this late one night, many years ago, and I only caught the last bit.
Thanks to the power of the internet, I saw the rest the other night.
Firstly, there's a pre-orange George Hamilton. He's a complete douche in the film and you quickly come to understand that half the things that happen to him are because he's such a dick to everyone.
Michael Rennie (post "The Day the Earth Stood Still") has a minor role in all this. Really, you wish he could be used more, considering the topic.
And Yvonne De Carlo is in this! Oh, come on, you remember who Yvonne De Carlo is. She plays a drunk widow in a trailer. It's great.
Getting back to the actual movie:
George Hamilton is a douche chemist who is gettin' it on with Suzanne Pleshette, his geneticist co-worker. They're working together to train a "superman" for their rocket tests.
Arthur O'Connell freaks out because there's a superman in their test subjects.
Predictably, people start to die.
Georgie boy goes on the run from cops who never take their hats off. They tell him to not leave town, so he leaves town and is almost killed.
Back in town from his near-killin', George runs into Suzanne Pleshette's land-lady, who has a polydactyl cat. Just an odd thing I noticed.
There's a car-crash, a fire, and a shoot-out. It's a strange film produced by George Pal, and that only shows in the last few minutes.
You can't get it on Netflix, but a copy is available on Amazon and Pirate Bay.
I won't tell you how to live your life. You do what you think is right.
You'll want someone to remake this this, with a whole new soundtrack.
