Kurt Cobain is the focus of a new documentary that probes the life and untimely death of the Nirvana singer-guitarist.
It will be released in cinemas next year and air exclusively on HBO, the network said.
Co-produced by HBO Documentary Films, Kurt Cobain: Montage of Heck is the first documentary made with the cooperation of Cobain's family. It will draw on home movies, journals and other personal archives.
It will feature Nirvana songs and performances and previously unheard Cobain originals.
The film's director-producer, Brett Morgen, has previously made the documentaries Crossfire Hurricane, about the Rolling Stones, and The Kid Stays In The Picture.
Cobain formed Nirvana in 1985, and by the early 1990s was decreed the spokesman of Generation X. He committed suicide in 1994 at the age of 27.
