What does Mad Max: Fury Road look like without the computer-generated imagery? Pretty much the same as the finished product. The explosions, the flamethrowers, and the fire? Those were all real. The wrecks? All real. Witness this.
To be honest, the only thing that tells you this video of action clips comes from production reels and not the theatrical release is the sight of an occasional camera truck and the ropes that are harnessed to some of the stunt guys. And a ramp and some traffic cones. The CGI department took more out of the film than they added in. -via reddit
