Animation Historical and Contemporary Practice: Tron

The first usage of CGI in a movie was in the Sci-Fi film Tron in the sequence where two opponents battle it out in a virtual reality set inside a video game where they drive in motorbike-like vehicles to cut each other out.

When John Lasseter saw this movie he said he was 'blown away', not by the film itself, but the potential of the technology used in the film.
