Ulrich made the comments during a question and answer session following the film's premiere at the Toronto International Film Festival. The band has released the video footage of the session.

Ulrich said, "Between 'Some Kind of Monster' and this, those are two pretty cool bookends � two opposite ends of the spectrum. Every time we do this it's a hell of a ride. � But you have to understand, getting a chance to do all these challenges and adventures really fuels us to go back into the studio and make hopefully a better album."

He added, "Metallica I think increasingly depends on these types of things to feel challenged as artists. So making films is great and it certainly gets us out of our comfort zone, so when we get back to the studio we just feel more inspired and more invigorated."
