I've noticed EACH Mad Max installment features action scenes based on one natural element. I know it can sound kinky or weird, and it wasn't done deliberately from Miller's part (I guess), but somehow unconscious played a big role in this.
MAD MAX 1: if you notice, fire is the central theme of the action sequences, and even of the plot itself. Nightrider burns in a big explosion. Goose burns in a fire. Johnny the Boy dies in a big mushroom-like explosion. And Max's character is driven by "young fire": revenge and passion. This is the chapter of damnation (= hell= FIRE).
MAD MAX 2: the central element is earth. All the action sequences are "well-grounded", so to speak. EVEN the only aerial vehicle of the movie (The GyroCopter) crashes on earth, its wings broken forever. The tanker was filled with sand. This is the chapter of redemption, and redemption requires crawling (ironically, Max's crawling like a worm right after the Interceptor blew up).
MAD MAX 3: of course! Air. The opening of the movie is very emblematic IMHO. The Thunderdome sequence is an "aerial" fight, circus-like, where the opponents "float" in the air and try to reach each other. The 747 plane is the symbol of the movie. Flying, as reaching the heaven (your paradise/promised land). Even the Audition (in Aunty's Penthouse) features acrobatics. And, more importantly, the chase scene was very acrobatical, with Max jumping, the characters jumping or hanging from poles and... the final stunt, where Powderbeast (Max's car) almost literally flies. This is the chapter of the ascension. Plus, this movie is lighter than the others, not "heavy" like Mad Max 2.
I'm expecting a FURY ROAD movie being based on water (not Waterworld!). If it's not a reboot.
