I assume you have seen Mad Max: Fury Road by now. If not, just stop reading and go and see it. It is absolutely superb. As well as being ridiculously entertaining, it is without a doubt one of the most visually spectacular movies ever made. That is quite a lot of hyperbole but I stand by it. Definitely see it in a cinema if you can.
If you have seen the film, I’m sure you’ll have assumed a fair amount of blue screen. There was some blue screen, but not as much as I initially thought going by the behind-the-scenes clip below. The clip is 18 minutes long but is pretty damned interesting. It is the B Roll and contains some interesting scenes showing how certain parts were made. It turns out there are a lot of brave stunt men, George Miller is a superb director, and the variety of ways you can shoot with a camera these days is highly creative. I feel I should reiterate at this point that you should go and see Mad Max: Fury Road, if you haven’t already.
(*Please note that there is no audio until about 50 seconds in, but it doesn’t matter much.)
