"We've had this idea in our minds for years and years and IMAX came to us over 10 years ago saying, 'We'd love to capture the intensity of the Metallica show with the energy that your fans create,'" he said. "[This was] back when they were doing the National Geographic-style climbing Everest and things like that it didn't work out for some reason."

Eventually the two camps would meet and hatch a new idea: "Basically they married up and eventually we funded it ourselves and went out there and made this amazing stage, like the Swiss Army Knife of stages that has every prop from every single tour that we've done from the crosses to the coffins to the destruction scene and it is certainly the most dangerous stage ever built. There was plenty of places to get caught up, electrified, burnt, statues crumbling� But capturing it on 3D and in IMAX and the sound is incredible. It's a bombarding of your senses."

"So, this is like seeing every Metallica tour all at the same time," Bean asked. "Pretty much," Hetfield responded. "For all those that didn't get to see Kill 'Em All, Master of Puppets, we have all those props and there's a story line to give it longer legs so it's just not a concert footage film. There's a lot of metaphors in this movie that will challenge the mind."

"We're super proud of this thing and it has been a labor of love. It's like releasing your baby into the world."
