Morgen, who is working on the film with Cobain and Love's daughter Frances Bean, said he decided not to give the 'Hole star' control over Montage of Heck, because she features in the documentary, said The Hollywood Reporter.
"At a certain point, I started working more closely with Frances Bean and we agreed that because Courtney was a subject in the film, it would be best if she wasn't given editorial control," he said.
Love initially brought the film idea to Morgen in 2007 after he impressed her with his 2002 Robert Evans biopic, 'The Kid Stays in the Picture', and she gave him access to her personal archives.
