The Brain is a 1988 Canadian science fiction horror film depicting a giant brain-like alien that mentally enslaves a town's residents.
Dr. Blake runs Independent Thinking, a television show promoting a self-help, quasi-religious program resembling Scientology.
But Blake is not making his audience think any more independently – with the help of an alien organism he calls The Brain, he is using brainwashing and mind control.
The only thing that stands between them and world domination is a brilliant but troubled high school student, named Jim Majelewski, with a penchant for pranks.
[1] A contemporary review for Variety called the film a "cliche-ridden effort, with little comic or ironic relief to put a spin on its sci-fi banalities", adding that its "ambition to comment on the power of TV and gullibility of its viewers vanishes quickly.
