The Lawnmower Man is a 1992 film which uses elements from the writings of Stephen King, most notably the short story "The Lawnmower Man".

The film's original script, written by director Brett Leonard and producer Gimel Everett, was titled Cyber God and had nothing to do with Stephen King. New Line held the film rights to Stephen King's short story, and decided to combine Cyber God with some very minor elements of King's story. The resulting film, originally titled Stephen King's The Lawnmower Man, differed so much from the source material that King sued the filmmakers to remove his name from the title. After two court rulings in King's favor, New Line still did not comply and initially released the home video version as Stephen King's The Lawnmower Man. A third ruling granted the author $10,000 per day in compensation and all profits derived from sales until his name was removed. On King's official web-page, it is not listed among the films based on his work. The film was released in Japan under the title Virtual Wars.

An earlier short film also titled The Lawnmower Man, and a more faithful adaptation of the short story, was directed by Jim Gonis in 1987.

A scientist performs experiments involving intelligence enhancing drugs and virtual reality on a simple-minded gardener. He puts the gardener on an extensive schedule of learning, and quickly he becomes brilliant. But at this point the gardener has a few ideas of his own on how the research should continue, and the scientist begins losing control of his experiments. Written by Ed Sutton
