The Matrix, Behind The Scenes

The Wachowski Brothers were keen that all involved understood the thematic background of the movie. For example, the book used to conceal disks early in the movie, Simulacra and Simulation, a 1981 work by the French philosopher Jean Baudrillard, was required reading for most of the principal cast and crew.
Comic book artists Geof Darrow and Steve Skroce worked on The Matrix as concept and storyboard artists respectively.
• Production design
In the film, the code that comprises the Matrix itself is frequently represented as downward-flowing green characters. This code includes mirror images of half-width kana characters and Western Latin letters and numerals. Generally, the film's production design placed a bias towards its distinctive green color for scenes set within the Matrix, whereas there is an emphasis on the color blue during the scenes set in the real world. In addition, grid-patterns were incorporated into the sets for scenes inside the Matrix, intended to convey the cold, logical and artificial nature of that environment.
