The below is in regards to the original TRON movie released in 1982

In the year it was released, the Motion Picture Academy refused to nominate Tron for a special-effects award because, according to director Steven Lisberger, “The Academy thought we cheated by using computers”.  The film did, however, earn Oscar nominations in the categories of Best Costume Design and Best Sound (Michael Minkler, Bob Minkler, Lee Minkler and James LaRue).  In 1997, Ken Perlin of the Mathematical Applications Group, Inc. won an Academy Award for Technical Achievement for his invention of Perlin noise for Tron.

In 2008, Tron was nominated for AFI’s Top 10 Science Fiction Films list
