Here's the trailer for Metallica Through the Never, Predators director Nimród Antal's attempt at giving Metallica the 3D treatment they've until now only found in high school notebook margins. In the film, METALLICA ROCKS. Also, Chronicle and Amazing Spider-Man 2's Dane DeHaan gets in a van accident, police and rioters fight, and there's a guy on a horse, and somehow all that is ostensibly involved in the periphery of this concert experience. That's why the band can tell themselves this isn't Bieber-inspired.
Here's the official synopsis, to almost lend clarity to what is happening:
Trip, a young roadie sent on an urgent mission during Metallica's roaring live set in front of a sold-out arena. As the band performs its most iconic songs for thousands of their fans in a never-before-seen performance created exclusively for the film, Trip is dispatched outside the arena to meet a disabled delivery truck and recover a mysterious item being transported to the show. But the seemingly simple assignment turns into a surreal adventure when his car is hit by an out-of-control driver. Trip, dazed and bruised, climbs out of his van only to find himself pitched in the middle of a tense standoff between angry protesters and charging riot police. In the ensuing mayhem, a vicious masked horseman sets his murderous eye on Trip while delivering indiscriminate deathblows to rioters and cops alike. Fleeing through the desolate, post-apocalyptic urban streetscape, Trip has only his wits to protect him as he attempts to deliver the band's precious cargo and avoid becoming the horseman's next victim.
So... the horseman probably represents file-sharing?
