The aliens, covered in slime
would conquer one brain at a time
They'd take Illinois
then the world they'd destroy...
Too bad that the script was a crime
The Brain Eaters (Bruno VeSota, 1958) is a science
fiction-horror film about alien parasites seeking to control
the population of a small town in Illinois. Gordon Urqhart's
script was based on Robert Heinlein's novel The Puppet
Masters. Heinlein sued producer Roger Corman, who
settled out of court.
