Between July 28 and Aug. 11, 2012, Metallica played eight shows at the Sports Palace in Mexico City. Not only did those concerts introduce a colossal stage setup that featured 1 million LEDs, live electricity onstage and a massive Lady Justice, they served as the warm-up gigs for the Canada shows that were ultimately filmed for the new 3D movie 'Metallica Through the Never.'

Above is the exclusive premiere of the eighth chapter in the band's behind-the-scenes series 'Hit The Lights: The Making of Metallica Through The Never.' This segment chronicles the band's time in Mexico City, with a particular focus on the fans, who essentially got a sneak peek at 'Metallica Through The Never' before everyone else.

From hearing fans exclaim their love for Metallica to getting an insider's view of what these shows were like, this edition of 'Hit The Lights' might be the coolest yet. Who can argue with how the fans feel? "Without Metallica, I do not live," says one fan. Another fan excitedly tells the camera, "Seeing them live is a dream." Yet another fan declares that Metallica is "the best show in the world in all of history!"

These dress rehearsals were unprecedented. Without them and the more than 170,000 Metallica fans that attended the shows, 'Metallica Through The Never' likely would never have gotten to the big screen.

'Metallica Through The Never' -- which hits IMAX 3D screens today (Sept. 27) and standard 3D screens on Oct. 4 -- is a movie just as unprecedented as the live shows it took to prepare for it. Loudwire and Noisecreep have partnered with Ultimate Classic Rock and Screencrush to bring you the exclusive featurette above.
