George Miller reportedly to begin shooting Fury Road sequel this fall

Came here to ask that too!

Which isn’t relevant if filming is in Australia or Namibia.

Honestly not driving trollies (not that I ever would!), but I identify with that description too. It was spectacular and cinematic, but that alone isn’t sufficient. Like @Wanderfound, I was disappointed by the underdeveloped (or understated?) worldbuilding.
I suspect those already into dieselpunk would get more from it, possibly because they’d get the shorthand of the genre conventions.

I totally respect the views of others, but I’m not automatically up for a sequel.
