The Batman: 7 Reasons George Miller Must Replace Ben Affleck
8. He Knows How To Be Theatrical
Looking at Mad Max: Fury Road - and indeed the whole Mad Max franchise - the biggest take-away is that George Miller knows how to be theatrical. He knows how to balance pomp and circumstance with compelling, at times jaw-dropping spectacle that grabs audiences by the lapels and drags them irresistibly in.
Imagine a Gotham City cut in Miller's image, sharing some of Thunderdome's weird, incestuous system of self-governance and its army of freaks within the walls. There's definitely something in that scorched-Earth dystopian future that lurks beneath the surface of Gotham, and which also fits the special brand of Gothic theatricality that worked so well for Tim Burton's vision of the dark knight.
Thinking more about theatrical impact, Miller's characters in Mad Max are all based on the same mechanics of impact as Batman: they make themselves look fearsome, build mythologies around themselves (or in Max's case, see it happen around them) and they're all about appearances. It wouldn't even be too much of a stretch for Batman to inhabit the same world. Both he and the director fit.
