The Matrix, Behind The Scenes

The objective of the bullet time shots in The Matrix was to creatively illustrate "mind over matter" type events as captured by a "virtual camera". However, the original technical approach was physically bound to pre-determined perspectives, and the resulting effect only suggests the capabilities of a true virtual camera.
The evolution of photogrametric and image-based computer-generated background approaches in The Matrix's bullet time shots set the stage for later innovations unveiled in the sequels The Matrix Reloaded and The Matrix Revolutions. Virtual Cinematography (CGI-rendered characters, locations, and events) and the high-definition "Universal Capture" process completely replaced the use of still camera arrays, thus more closely realizing the "virtual camera".
• Music
The film's score was composed by Don Davis. He noted that mirrors appear frequently in the movie: reflections of the blue and red pills are seen in Morpheus's glasses; Neo's capture by Agents is viewed through the rear-view mirror of Trinity's Triumph Speed Triple motorcycle; Neo observes a broken mirror mending itself; reflections warp as a spoon is bent; the reflection of a helicopter is visible as it approaches a skyscraper. (The film also frequently references the book Alice's Adventures in Wonderland, which has a sequel entitled Through the Looking-Glass.) Davis focused on this theme of reflections when creating his score, alternating between sections of the orchestra and attempting to incorporate contrapuntal ideas.
