Without the Dialogue you miss a lot of the culture of “that world” and no Mad Max film has ever been silent before.
A good portion of Mad Max 2 is silent.
I’m sure I’ll check out Fury Road in silent mode at some point (provided it’s a separate audio track as promised), but I’m indifferent towards the idea. Seeing it in Black & Chrome is what I’m really pumped about. I bet it’ll look awesome that way, and as good as the theatrical release was, I was already pretty tired of Orange & Teal at that point.
