A simple man is turned into a genius through the application of computer science.
The Lawnmower Man is a 1992 science fiction horror film directed by Brett Leonard, written by Leonard and Gimel Everett, and starring Jeff Fahey as Jobe Smith, an intellectually disabled gardener, and Pierce Brosnan as Dr. Lawrence "Larry" Angelo, a scientist who decides to experiment on him in an effort to give him greater intelligence by stimulating his brain using nootropic drugs and virtual reality computer simulations. The experiments give Jobe superhuman abilities, but also increase his aggression, turning him into a man obsessed with evolving into a digital being.
