===Filming===
''The Matrix Reloaded'' was mostly filmed at [[Fox Studios Australia|Fox Studios]] in [[Australia]]. Filming began on March 1, 2001 and ended on August 21, 2002, concurrently with the filming of the second sequel, ''[[The Matrix Revolutions|Revolutions]]'' and the live-action footage for the ''[[Enter the Matrix]]'' video game. The [[freeway]] chase and "Burly Brawl" scenes were filmed at the decommissioned [[Naval Air Station Alameda]] in [[Alameda, California]]. The producers constructed a 1.5-mile freeway on the old runways specifically for the film. Some portions of the chase were also filmed in [[Oakland, California]], and the tunnel shown briefly is the [[Webster Tube]], which connects Oakland and Alameda. Some post-production editing was also done in old aircraft hangars on the base. The city of [[Akron, Ohio]] was willing to give full access to [[Ohio State Route 59|Route 59]], the stretch of freeway known as the "Innerbelt", for filming of the freeway chase when it was under consideration. However, producers decided against this as "the time to reset all the cars in their start position would take too long".<ref name=job>{{cite web |url=http://autos.msn.com/advice/article.aspx?contentid=4021949&src=News |title=Chasing the Stars: Carmakers in Movies |publisher=MSN.com |first=Ann |last=Job |access-date=2005-01-30 |archive-url=https://web.archive.org/web/20050306233023/http://autos.msn.com/advice/article.aspx?contentid=4021949&src=News |archive-date=March 6, 2005 |url-status=dead }}</ref> [[General Motors]] was hired to donate over 300 cars to be used during production, destroying them for the sake of creating art.<ref>{{cite web|url=https://www.motorbiscuit.com/300-gm-cars-completely-destroyed-during-matrix-reloaded-highway-chase-scene/|title=Over 300 GM Cars Were Completely Destroyed During 'The Matrix Reloaded' Highway Chase Scene|date=March 10, 2022|access-date=July 5, 2022|archive-date=May 18, 2022|archive-url=https://web.archive.org/web/20220518041436/https://www.motorbiscuit.com/300-gm-cars-completely-destroyed-during-matrix-reloaded-highway-chase-scene/|url-status=live}}</ref> ''[[MythBusters]]'' would later reuse the Alameda location in order to explore the effects of a head-on collision between two semi trucks, and to perform various other experiments.

===Visual effects===
Following the success of the previous film, the Wachowskis came up with extremely difficult action sequences, such as the Burly Brawl, a scene in which Neo had to fight 100 Agent Smiths. To develop technologies for the film, Warner Bros. launched ESC Entertainment.<ref name="Wired VFX" >{{cite magazine | url=https://www.wired.com/wired/archive/11.05/matrix2_pr.html | title=Matrix<sup>2</sup> | magazine=Wired | access-date=December 25, 2012 | author=Silberman, Steve | archive-date=January 15, 2013 | archive-url=https://web.archive.org/web/20130115105744/http://www.wired.com/wired/archive/11.05/matrix2_pr.html | url-status=live }}</ref> The ESC team tried to figure out how to bring the Wachowskis' vision to the screen, but because bullet time required arrays of carefully aligned cameras and months of planning, even for a brief scene featuring two or three actors, a scene like the Burly Brawl seemed almost impossible as envisioned and could take years to composite. Eventually [[John Gaeta]] realized that the technology he and his crew had developed for ''The Matrix''{{'}}s [[bullet time]] was no longer sufficient and concluded they needed a [[virtuality|virtual]] [[camera]] (in other words, a [[simulation]] of a camera). Having before used real photographs of buildings as texture for 3D models in ''The Matrix'', the team started digitizing all data, such as scenes, characters' motions, or even the reflectivity of Neo's [[cassock]]. The [[reflection (computer graphics)|reflectivity]] of objects needs to be [[Bidirectional scattering distribution function|captured and simulated adequately]] and [[Paul Debevec]] et al. captured the reflectance of the [[human face]] and Borshukov's work was strongly based on the findings of Debevec et al. They developed "Universal Capture", a process which samples and stores facial details and expressions at high resolution, then capture expressions from Reeves and Weaving using [[Motion capture#Markerless|dense capture]] and [[multi-camera setup]] (similar to the bullet time rig) [[photogrammetry|photogrammetric]] capture [[Art techniques and materials|technique]] called [[optical flow]].<ref name="Deb2005">{{cite book | last = Debevec | first = Paul | author2 = J.

With this collected wealth of data and the right algorithms, they finally were able to create [[virtual cinematography]] in which characters, locations, and events can all be created digitally and viewed through virtual cameras, eliminating the restrictions of real cameras, years of compositing data, and replacing the use of still camera arrays or, in some scenes, cameras altogether. The ESC team rendered the final effects using the program [[Mental Ray]].<ref name="Wired VFX" />

===Music===
{{See also|The Matrix Reloaded: The Album|The Matrix Reloaded (score)}}
[[Don Davis (composer)|Don Davis]], who composed for ''The Matrix'', returned to score ''Reloaded''. For many of the pivotal action sequences, such as the "Burly Brawl", he collaborated with [[Juno Reactor]]. Some of the collaborative cues by Davis and Juno Reactor are extensions of material by Juno Reactor; for example, a version of "Komit" featuring Davis' strings is used during a flying sequence, and "Burly Brawl" is essentially a combination of Davis' unused "Multiple Replication" and a piece similar to Juno Reactor's "Masters of the Universe". One of the collaborations, "[[Mona Lisa Overdrive (song)|Mona Lisa Overdrive]]", is titled in reference to the [[cyberpunk]] [[Mona Lisa Overdrive|novel of the same name]] by [[William Gibson]], a major influence on the directors.

[[Leitmotif]]s established in ''The Matrix'' return — such as the Matrix main theme, Neo and Trinity's love theme, the Sentinel's theme, Neo's flying theme, and a more frequent use of the four-note Agent Smith theme — and others used in ''Revolutions'' are established.

As with its predecessor, many tracks by external musicians are featured in the movie, its closing credits, and the soundtrack album, some of which were written for the film. Many of the musicians featured, for example [[Rob Zombie]], [[Rage Against the Machine]] and [[Marilyn Manson (band)|Marilyn Manson]], had also appeared on the soundtrack for ''The Matrix''. [[Rob Dougan]] also re-contributed, licensing the instrumental version of "[[Furious Angels]]", as well as being commissioned to provide an original track, ultimately scoring the battle in the Merovingian's chateau. A remixed version of "[[Slap It (Fluke song)|Slap It]]" by electronic artist [[Fluke (band)|Fluke]] — listed on the soundtrack as "Zion" — was used during the rave scene.

[[Linkin Park]] contributed their instrumental song "Session" to the film as well, although it did not appear during the course of the film. [[P.O.D.]] composed a song called "[[Sleeping Awake]]", with a [[music video]] which focused heavily on Neo, as well as many images that were part of the film. Both songs played during the film's credits.

It was originally planned for the electronic band [[Röyksopp]] to create the soundtrack, but this offer was turned down.<ref>"[http://www.fib.no/en/News-2015/Kafka-feat-Royksopp-at-the-Bergen-International-Festival/ Kafka feat.
