The main filming of "The Matrix 2: Reloading" and "Matrix Revolution" were all done in Australia. Due to the huge project, the two films provided a total of 3,500 jobs for the local area, employing 80 full-time actors and hundreds of Thousands of extras. In the art department, production designer Irving Patterson employed more than 400 people to complete 150 sets of the two films.
The highway on which the car chase scene was filmed was not an existing highway that was closed, but was specially paved by the crew. This section of highway, which is only one and a half mile long, was actually rebuilt on the airstrip of the Amanda Naval Base, including two Sky bridge and a 19-foot concrete wall.
Patterson’s department often produces two or three versions of the same scene to reflect the damage at different stages, and many scenes like the Merovingian castle need to be able to withstand a lot of action. In addition, Patterson's department also designed a large number of rubber weapons for the film. They used casting and painting methods to make these complex-shaped rubber weapons, and because the damage rate was very high, they had to keep making them.
