Mad Max (1979, American International, dir. George Miller) was a famous franchise of futuristic motorcycle movies filmed in Australia.
But in 2015 George Miller provided us with IV: Mad Max: Fury Road with Tom Hardy, Charlize Theron, and Nick Lathouris, filmed in Namibia. Village Roadshow Pictures and Warner Brothers gave us this one.
Tyler Mowery, in a April 2021, analyzed this film in a video titled "How to Write a Story with Dual Protagonist".But in May 2022 he offered a video "Why You Shouldn't Have Two Protagonists".
Well, that's not quite the same as "dual protagonists". A protagonist drives the story forward. is the reason for the movie to exist (it gets messy if you try to explain a historical mystery from the viewpoint of an obscure protagonist thought to observe but who actually drove the action affecting someone more obviously visible -- who was also driving action.) Dual protagonists work in buddy movies where both have equal weight (like "Bonnie and Clyde" or "Butch Cassidy and tje Sundance Kid"), or in a family generational movie, where the wand passes on ("Sunshine", 2000, going through fascism and communism) -- or even "Godfather" series). My own "do ask do tell" extract "Williamsburg and Charlotte" does that with my parents and then me. You have to have real transition points to make a switch.
