The film will premiere May 4 on HBO. Billboard spoke to Morgen earlier this year about the upcoming release, which he worked on over a span of eight years.

"It's as intimate you can get," he said. "People have projected fantasies on the limited amount of things that came out between 1991 and 1994 (from Cobain). I have a great degree of confidence the more you get to know him, the more you'll love him."
