Loosely based on a short story by Stephen King,
The Lawnmower Man
was the first film to explore virtual reality technology and boasts a dazzling collection of computer-animated sequences. The story concerns the slightly-mad scientist Dr. Lawrence Angelo (Pierce Brosnan), who as part of a secret government agency called Cybertech has been experimenting with something termed "intelligence enhancement." By using drugs and virtual reality technology, Angelo has managed to boost the IQ of experimental chimps. But he also makes them more aggressive and, bit by bit, they go insane. When one of his animal subjects goes on a rampage, Angelo decides to go for a human guinea pig instead -- Jobe Smith (Jeff Fahey), a slightly retarded man who cuts his lawn. Not only do Jobe's intelligence and sex-drive improve thanks to Angelo's regimen, but he also develops extrasensory perception. As Jobe's mental and emotional state keeps increasing, so does his strength. As he gains more power, Jobe becomes angrier and more vindictive until he vows to get even with all the town's people that patronized him and treated him badly.
