With Cobain’s daughter Frances Bean Cobain acting as executive producer, the documentary - which contains footage which has never been seen before - started in 2007 when the late musician's wife Courtney Love approached Oscar-nominated filmmaker Brett Morgen.
Love is said to have provided an archive that included home videos, audio tracks, audio diaries and around 4,000 pages of Cobain’s journals.
"People didn't realize how very funny Kurt Cobain was, or how romantic he was, or what a doting father he was. Ultimately the mythology of the man is that he was in pursuit of fame, and then he didn't want fame anymore. I hope this film shatters that illusion.
“I think Kurt, the child of a divorce, was in pursuit of family his whole life, and when that became defiled that's what ultimately led him to take his own life. But I didn't make this film for fans. I made it for Frances."
