Brett Morgen: I worried about working with Love

Brett Morgen was apprehensive about working with Courtney Love.

Brett is the director of new documentary Kurt Cobain: Montage of Heck, which pulls together footage of Kurt and interviews with those that knew him, charting his early days in Washington to Nirvana's success and his death. It features interviews with Courtney, who was married to Kurt when he committed suicide in 1994.

"I guess I was apprehensive about working with her given her reputation," Brett confessed to American GQ. "And as it turns out I didn't have to work with her. I made it a point to require final cut, which I felt was essential given the history, since Kurt's death, with Nirvana. So that gave me a level of protection that certainly diluted any concerns I might have had."

Courtney approached Brett in 2007, and after seeing his previous work decided he was the man to tell Kurt's story.

However the filmmaker ultimately worked with Kurt and Courtney's daughter Frances, 22, on the project, where she served as executive producer. It took years to bring it to the big screen, with legal battles in Courtney and Frances' personal life hampering production. There were even points where Brett thought the documentary was a lost cause.

"Most of those years were spent with legal manoeuvrings and acquiring rights. There was a point in which Frances and Courtney were battling things out in court, and during those - I think it was about two years - everything was frozen. It was one of these things where there were months at a time where I just assumed the movie was never happening, and then I'd get a call. It really wasn't until a trustee was appointed, I think in 2011 or 2012, that things really started to move forward," he explained.
