That's right -- that last guy, whom you've never heard of, was already in a Mad Max. He played the villainous Toecutter back in 1979, when Gibson was still Australian. Miller is taking absolutely no chances with this reboot -- he wants a man he can trust to be snarling and murderous (which would explain why he stuck with Gibson for an entire decade). Keays-Byrne isn't playing the squashed zombie of his previous character, though -- he plays the primary antagonist, a brand-new villain named Immortan Joe.

He politely declined Hardy's suggestions for making the masked vocals work.
The cast is rounded out by a bunch of X-Men and that British lady from Transformers 3 who was somehow worse than Megan Fox. Tossing the lot of them into a sea of vehicular violence in the middle of the desert seems like the perfect recipe to chase the summer blues of 2015 away.

The Story: Screw the Story, CAR CHAAAAASE
So what is Mad Max: Fury Road? Is it a remake? A prequel? A sequel?
Nobody has any idea, really, because all Miller has told us is that it's going to be a 110-minute-long car chase. He said in an interview: "I wanted to tell a linear story -- a chase that starts as the movie begins and continues for 110 minutes. ... In this crucible of very intense action, the characters are revealed." So, basically, it's just going to be one giant clusterfuck parade of cars tearing across the Australian outback, characters exploding in and out of existence, and flaming motorcycles pinwheeling off into the sky while a Tina Turner power ballad blasts our eardrums (hopefully).

Who needs dialog when there are stunt cars to smash?
