Trivia: According to director George Miller, 90% of the special effects in the movie were practical. CGI was required only for certain elements, such as Furiosa's arm, removing stunt rigs and enhancing the sky.
Trivia: The interceptor being rolled at the start was driven by the same stuntman that did the famous bike crash in Mad Max 2 where the rider is catapulted over the crashed car - the interceptor roll was a nod to that stunt. He also rolled the War Rig at the end. Mad Max 2 was the first film he worked on, and Fury Road was his last - he retired afterwards.
Trivia: Furiosa's false arm was made of metal for the close up scenes when she is not wearing it and several versions were made of foam rubber and soft leather for the action scenes. It's CGI when attached.
