With that extra shooting, which Tom Hardy described as making the film even better, the studio has had a mostly finished cut turned in for a while now. So they did what any big business would do - they showed it to a focus group basically. Of course in movie land those are called "test screenings" and participants sign all sorts of non-disclosure agreements which are almost immediately broken when they start posting comments online. Thus was the case with Mad Max: Fury Road, and the world of mouth from the test screening was very, very good. That's impressive for a film not 100% finished. And no other film due in 2015 has this kind of advanced word of mouth going for it.
