Which isn't totally surprising: The Bay Area foursome was pretty darn hesher, especially back in the days when bassist Cliff Burton was in the band, before he died tragically in a 1986 bus accident. Back then, Metallica was drink, grow hair, play metal. Repeat. Maybe add a little drugs and women, then repeat again. What more needeth a real and true hesher?
Apparently, though, the Hesher film did a very good job of capturing Burton in the character that Gordon-Levitt plays. Like, a good enough job that Metallica itself expressed approval.
He says, via Metal Underground:
[Metallica] dug the movie. It was a real honor and I took a lot of inspiration for this character from the basis of some of their early albums [and] this guy named Cliff Burton, who played on Master of Puppets and Ride the Lightning. And when the band saw it, they were like, 'You know what?! He reminds us of Cliff,' and we didn't even tell them that's what we were going for. And they let us use their songs and I was actually moved because I grew up headbanging to Metallica.
There you have it. Hesher, by the way, comes out May 16. We'll leave you with Cliff, doing it like only he could:
