Kurt Cobain: Montage of Heck, produced by the late Nirvana singer’s daughter Frances Bean Cobain, was screened Saturday at the Sundance Film Festival and offered a bittersweet moment between Kurt Cobain’s daughter and his widow.

The occasion reunited Kurt Cobain’s only daughter with her estranged mother Courtney Love for the screening, after several years of estrangement.

The mother and daughter alienation reportedly stems from accusations that were made by Courtney Love several years ago that former Nirvana drummer Dave Grohl hit on Frances.

However, the estranged mother and daughter exchanged a warm hug for the premiere of the documentary and a moment of commonality in their love of Kurt Cobain, who died of an apparent suicide in 1994.

Courtney Love lost legal control of her daughter in 2009, and three years later, accused the drummer of coming on to her daughter. Frances denied the allegations, calling them “gross.”

Kurt Cobain’s 22-year-old daughter is the executive producer of the documentary and interestingly enough, Dave Grohl doesn’t even appear in the film, even though he was reportedly interviewed for the production.

Apparently, an interview conducted for the film came too late to make it into this version of the documentary, but may make it into the cut for the HBO release on May 4.

“We had a locked print and trying to re-edit a film with a new interview in 10 days is kind of difficult,” director Brett Morgen explained at the premiere at the Marc Theater. “This is the picture I wanted — I didn’t want there to be a lot of people in the film. I hope we’ll see a version [with the Grohl interview] some time.”
