One of the actors appearing in Metallica's 3-D film has some high expectations for the finished product. Dane DeHaan, who plays a crew member, tells Collider.com, "During the concert, I basically go on this trip as a roadie for the band and I pretty much literally have to go through hell and back to take it back to them... It's unlike anything that I've ever seen before; it's almost like a concert movie meets The Wall meets Metallica." Metallica Through the Never is due out August 9th.
