Alan Ritchson Shows His Grit in Behind-the-Scenes Look at Netflix's War Machine

New behind-the-scenes footage from the Netflix sci-fi thriller War Machine shows Alan Ritchson enduring a grueling training regimen modeled on Army Ranger Selection. Standing at a towering 6'3'' and seemingly made of steel, he and his fellow cast members are put through exercises designed to prepare them to face a mysterious war machine.

A caption alongside the footage reads, "Shoved into class V rapids, dragged through mudslides, blown off scenic mountaintops… we tried our best to break Alan Ritchson but he just won’t quit." The clip shows Ritchson smiling through what the piece describes as a hellish experience that many would quickly walk away from.

The first trailer positions Ritchson as Candidate 81, thrown into a deadly scenario described as part Predator, part War of the Worlds, with echoes of Battle: Los Angeles. War Machine picks up during the final 24 hours of the world's toughest selection program, as Ritchson's combat engineer must lead his unit against a giant otherworldly killing machine.
