Metallica's 2004 documentary 'Some Kind of Monster' made for interesting viewing, with the band members taking some heat for how they came off in the film. However, the documentary had a positive side effect when it came to the future of the band. Ten years later, drummer Lars Ulrich believes that the movie helped save Metallica from an eventual meltdown.

The drummer tells The Wrap, "The making of the movie was one of the most extraordinary experiences in my life, precisely because it came at such a vulnerable time. The presence of the cameras helped keep things on track -- there was another set of eyes and ears there. When somebody else is in the room, you watch your Ps and Qs a little more. I think it kept the whole thing from derailing."

Because the cameras were rolling, the band was forced to confront some of their communication issues and Ulrich recalls, "This was the first time we had to talk to each other, get to know each other and work stuff out."

The band is currently revisiting the documentary film for its 10th anniversary Blu-Ray reissue and Ulrich states, "There are always things that throw you for a loop. The fact that the music world was a little bewildered by it, and the facts that the movie world sort of embraced it, was not something we would have predicted."

Metallica's 'Some Kind of Monster' is newly available on Blu-Ray at this location. Meanwhile, the group continues to work on their next album, though no official release date has been announced.
