A previously unreleased photo of Kurt Cobain, featured in Montage of Heck

The first “fully authorized” documentary chronicling the meteoric rise and troubled personal life of Nirvana frontman Kurt Cobain is set to debut on HBO in 2015. Entitled Montage of Heck, the film is being directed by Brett Morgen (Chicago 10, The Kid Stays in the Picture) and features Cobain’s daughter, Frances Bean, as an executive producer.

According to a press release, Montage of Heck draws its title from a mixtape Cobain made in the late 1980s, an apt choice given that the music-centric film will make use of “dozens of Nirvana songs and performances as well as previously unheard Cobain originals.” The release adds that Montage of Heck will offer viewers “no-holds-barred access to Kurt Cobain’s archives, home to his never-before-seen home movies, recordings, artwork, photography, journals, demos, personal archives, family archives and songbooks.”

In a statement, Morgen said, “I started work on this project eight years ago. Like most people, when I started, I figured there would be limited amounts of fresh material to unearth. However, once I stepped into Kurt’s archive, I discovered over 200 hours of unreleased music and audio, a vast array of art projects (oil paintings, sculptures), countless hours of never-before-seen home movies, and over 4,000 pages of writings that together help paint an intimate portrait of an artist who rarely revealed himself to the media.”

Speaking with NME last January, Morgen said the film would feature “a mix of animation and live action that’ll allow the audience to experience Kurt in a way they never have before,” explaining that it “will be this generation’s The Wall.” Morgen also said that he hoped to portray a more nuanced Cobain, as he found the grunge icon to be a “contradiction,” adding “Cobain could be sincere and sentimental, and also ironic and sarcastic. He was sweet and sour. He was incredibly funny, too, and the film has to reflect his spirit.”

The documentary isn’t the only Cobain-related film in the works. As previously reported, Cobain’s wife, Courtney Love is in the midst of casting the lead role for a Cobain biopic, which she said will go into development next year.
