Director George Miller famously used primarily practical effects to achieve much of the film’s spectacle, so the visual effects used had to be potent.
“The reality is that there’s 2,000 VFX shots in the film,” visual effects supervisor Andrew Jackson told FXguide. “A very large number of those shots are very simple clean-ups and fixes and wire removals and painting out tire tracks from previous shots, but there are a big number of big VFX shots as well.”
