Nice flashback to 1999, love it!

I used to have the original DVD combo of all the Matrix franchise + Animatrix. In there were interviews with crew and filmmakers. I remember someone was telling the story behind how those scenes were shot where people sort of look like they'd been frozen a couple of meters or so above the ground - they used a revolutionary capture technique at the time: about 40 cameras that were all placed next to each other around the actor, forming a shape that would remind you a bit of a roller coaster turn in amusement park.

They did like Australia as a place for filming for some reason. I think they built 3 miles of highway there specifically for Matrix Reloaded shoot, but it got dismantled after the production finished.

Btw, what a lot of people don't realize nowadays is that the concept of people being able to connect to some sort of matrix via a cable connected to the back of the head comes from a cyberpunk novel, a classic of 1980s science fiction called Neuromancer.
