When we spoke to him about the new film Super Duper Alice Cooper, Sam Dunn revealed that he and his Banger Films production crew are working on documentaries about Soundgarden and a “legendary metal band that shall remain nameless for now.” Well now it turns out that said legendary band is Black Sabbath.

Banger Films co-founder Scot McFadyen let it slip during an interview with the Times Colonist that they’ve inked a contract to make a full-length documentary. Though it’s unknown as to when that documentary will see the light of day (or even begin filming), it’s yet another addition to Banger Films’ already busy schedule. This not only includes the mentioned Soundgarden doc, but also kids programming for the Family Channel and the creation of their own broadcast and online channel Banger TV.

Banger Films did a spectacular job documenting the history of metal and all its subgenres in Metal: A Headbangers’ Journey, and their films chronicling the legacies of Iron Maiden, Rush and most recently Alice Cooper are just as superb. So while there have been plenty of films about Black Sabbath, we have full faith that Banger Films will do a hell of a job with their take. Whether their film will focus on the original lineup or (gasp) actually touch upon the post-Ozzy years, though, remains to be seen.

To give you a taste of what you might be able to expect from their future Black Sabbath doc, check out = interviews with Tony Iommi and Ronnie James Dio they conducted for Metal: A Headbangers’ Journey below.
