It's certainly a surprising announcement, given that he has talked up plans for sequels while out promoting Mad Max: Fury Road (2015). But it seems the gruelling schedule of that movie has left him unwilling to make such a commitment again. "I won't make more Mad Max movies," he said at the Golden Globes. "Fury Road was forever getting completed. If you finish one in a year, it's considered a leap of faith. Start, stop, start again. I've shot in Australia in a field of wild flowers and flat red earth when it rained heavily forever. We had to wait 18 months and every return to the US was 27 hours. Those films take forever. I won't do those anymore."
That said, Miller could very well change his mind once he has had some distance from Mad Max: Fury Road and neither does it preclude him producing future instalments while handing over the reins to other filmmakers. Still, we would be sorry not to see another visit to the wasteland from the man who started the journey himself. As always, watch this space.
