Early versions of the film claimed that they were related to a Stephen King work. King did write a short story called "The Lawnmower Man", but it was completely different to the movie. King sued the film makers, and had his name removed from the film.
New Line Cinema released The Lawnmower Man (1992), and the producers had a script called Cyber God. They combined the two, using Stephen King's original title. King was furious at this abuse of his name and he sued the studio to have his name and title removed from the film and promotion. They refused until the studio was ordered to pay $10,000 and full profits.
Jenny Wright did only the close-ups in the VR strobe scene because the strobe light made her sick. Her wide-angle shots were done using a double, and the close-ups to her face were done with a blue screen so that she didn't have to move.
There are three video games based on the movie. Scrolling action game The Lawnmower Man (1993) for Game Boy, Genesis and SNES loosely follows the plot of the movie. FMV adventure game The Lawnmower Man (1993) for DOS, Macintosh and SEGA CD uses clips from the movie and is a direct sequel to the movie, since Its plot begins where the movie ends. Adventure game Cyberwar (1994) for DOS and PlayStation is a non-FMV sequel to the FMV game.
