Courtney Love didn't show up for the Sundance Film Festival screening of her new documentary

Festival director Eugene Hernandez told the crowd: "Unfortunately she's not able to make it to tonight's screening."

Co-director Edward Lovelace - who helmed the project with James Hall - added: "We're really gutted that Courtney couldn't make it tonight to celebrate this moment with us all."

He described Love as "so unfiltered" and "so truthful", while praising for trusting the team to "tell her story and allowing us to to experience the last three years".

He said: "We just wanted to say it's been the greatest of privileges to be invited into Courtney's personal space to make such an intimate honest film with someone we have so much love for."

In the film, fans will get an insight into Love's life in London after moving there five years ago, while she's starting to work on new music.

The logline reads: "Now sober and set to release new music for the first time in over a decade, Courtney is ready to reveal her story, unfiltered and unapologetic."

In a question and answer after the screening, Hernandez filmed the crowd applauding and shouting "we love you Courtney", as he promised to share the footage with the star.

The likes of Michael Stipe, Billie Joe Armstrong and Butch Walker appear in the film, and producer Julia Nottingham - who has worked on other documentaries like Pamela: A Love Story and Victoria Beckham - previously opened up on the goals behind the project.

She told Variety: "As a child of the 90s, I was always curious about Courtney, a woman who often appeared to be defined by her husband Kurt Cobain.

"We made this film because Courtney's story is bigger than the headlines. It's raw, complicated, and deeply human."
