When The Lawnmower Man was made, it was visually ahead of it’s time; A virtual world seen for the first time on the big screen, and it was awesome. It was also based on a short story by Stephen King – what more could you ask for? Maybe take out the plot and the acting? Done. Pauly Schniedy posted on YouTube a video of only the virtual reality in the movie and while it may not need to make sense on it’s own, it just needed to be made.
If you still don’t have enough of the virtual world, I highly recommend the Community episode, Lawnmower Maintenance and Postnatal Care.
