In the scene, Cobain is seen with baby Frances in his arms, barely able to keep his eyes open while under the influence of narcotics. Kurt's mother Wendy was not happy with the picture it painted of her son.

Morgen tells Billboard: "When Kurt's mother voiced some concerns about the way she was depicted, and the way Kurt was seen in the latter stages of his life, it was Frances who called and said, 'Grandma, this is not your film. This is Kurt's film, and how you experience things is quite different than the way Kurt experienced things.'

"I think the point was if we allow our mothers to dictate the content of our biographies they would be pretty nice. Of course the mother doesn't want to show her child in any light that's less than favourable. But it was Frances' desire to not hide the truth, and I think that both Frances and I arrived at the same point, which was we were not trying to tear Kurt down or put Kurt down, nor were we trying to put him on a pedestal.
