Lords of Chaos: The Bloody Rise of the Satanic Metal Underground is a book written by Michael Moynihan and Didrik Søderlind, and was originally published in 1998. The book chronicles the early black metal scene, which as you know includes the murder of Mayhem's Euronymous, various other killings, and some church burning.
According to an article published by Deadline, Vice Films, Insurgent Media, Chimney Pot and 20th Century Fox, are all partnering together for the movie, which will be directed by Jonas Åkerlund. A neat little fact about director Åkerlund is that he actually drummed for Bathory between 1983 and 1984.
The film will star Emory Cohen, Jack Kilmer and Sky Ferreira, alongside Rory Culkin who you might know from Signs and Scream 4. in the English-language film "Lords Of Chaos", based on true events in the Norwegian black metal music scene in the early 1990s. Insurgent Media's Ezna Sands said of the film:
"This is a premise with unique universal appeal, a kind of Trainspotting for the millennial generation, and Insurgent Media leapt at the opportunity to get 'Lords Of Chaos' onto the main stage. This is the start of a hugely exciting journey along with the teams at Fox, VICE and Scott Free."
The film will follow the life of Euronymous, which I'm sure is pissing Varg off to no end right now.
