Tom Hardy grimaces in close-up, his face constrained under a metallic muzzle, his arms pinned back, his body chained to a war machine racing right at the camera. There are countless jaw-dropping images in “Mad Max: Fury Road,” but none quite as memorable or definitive as the moment where fury meets road. More than just a snapshot of speed, danger and intensity, this instant captures the subversive edge of George Miller’s 2015 car-chase spectacular — how it turns one of cinema’s most iconic action heroes, the Outback outlaw Max Rockatansky, into a glorified hood ornament.
