The Lawnmower Man

Brosnan is a scientist who uses Fahey, a dim-witted gardener, as a guinea pig to test his experiments in "virtual reality," an artificial computer environment. With the use of drugs and high-tech equipment, Brosnan is able to increase Fahey's mental powers--but not necessarily for the better. Fantastic special effects and a memorable "virtual reality" sex scene. Available in an unrated version which contains 32 more minutes of footage. So minimally based on a short story by Stephen King that the author sued (and won) to have his name removed from the film.
