The as-yet-untitled story of the Nirvana star will be loosely based on the acclaimed 2002 biography Heavier Than Heaven by Charles R. Cross.
But Moverman is adamant he will not focus purely on Cobain’s drug addiction and death – he wants to show cinema-goers all aspects of the rocker’s world.

“It’ll be raw and chaotic, which is what Cobain’s life was like.”
