A Fox Studios insider told us today that George Miller’s "Fury Road : Mad Max 4" will be delayed. "(It has) definitely been delayed/postponed. No reason why", he says. We also found out one of the reasons why George Miller has decided to film the movie in Africa and not Australia. "The dunes that George Miller wants for his script dont exist in australia. For Thunderdome they did very little dunes work (walking only) at kurnell, which has undergone a vegetaion regrowth. Kurnell was also not big enough for large vehicle shots".
