Nowadays, it’s no big deal to see computer animation in films. In fact, the use of CGI in films can range from being mundane to being annoying. However, three decades ago, computer animation was in its infancy, and one of the biggest pioneers of its use in major motion pictures was Tron from Walt Disney Studios. Tron’s legacy led to the development and release of its sequel Tron: Legacy two years ago from Joseph Kosinski, and now the release of Kosinski’s latest film Oblivion. However, without the original Tron, we might not have the use of virtual environments that moviegoers are used to now. Dialing back the digital clock to 1982, let’s take a look at the original Tron through the eyes of its creators, whose ambitious little computer cartoon revolutionized an industry. Director Steven Lisberger, along with the producers and visual effects supervisors, recorded a commentary for the film for the 20th anniversary 2002 DVD, which is also available on the 2011 Blu-ray release.
