“There are four members in Led Zeppelin, four members in Metallica, it’s a full-length movie, and there’s a lot in this film that does not take place onstage. The major difference is that the stuff that takes place offstage in the Metallica movie does not feature any members of Metallica. It’s two separate worlds – a Metallica show and a story that unfolds in a parallel universe – and at some point they intertwine.”
The film is expected to be in theaters this summer.
