Arthur Cave fell to his death onto the underpass of Ovingdean Gap in Brighton on 14 July 2015. An inquest heard he had taken the hallucinogen LSD before plunging from the cliff and suffering a brain injury – he was taken to the Royal Sussex County hospital where he later died.

Now, singer father Nick Cave continues to deal with the subject of grief in his work and has created a documentary about the making of his new album, Skeleton Tree.

New Zealand born filmmaker Andrew Dominik directed One More Time with Feeling, which captures the making of the record. The film had its world premiere at the Venice Film Festival on Monday and Dominik claimed that Cave wanted to make the documentary to avoid discussing the painful subject of his son Arthur's death with the media.

Dominik, 48, told journalists at the film event: "Nick went into a newsagent in Brighton and saw a copy of Mojo; he realised he was going to have to promote the record.

"Arthur had died halfway through making it. And the idea of [promoting] it made him feel sick, because he was going to have to discuss the context of the record with a whole bunch of journalists.

"That prospect was very alarming to him. His instinct in making the film was one of self-preservation: it was a way to talk about what happened, but there was a certain safety in doing it with someone he knew," he continued.

The feature film – which is shot in aesthetically-pleasing black and white and in 3D, will screen in cinemas for one night only on September 8. It will launch Nick Cave and the Bad Seeds album, Skeleton Tree. The documentary will release worldwide on September 9.

At the time of Arthur's death, Nick released a statement with his wife Susie. They said: "Our son Arthur died on Tuesday evening. He was our beautiful, happy loving boy. We ask that we be given the privacy our family needs to grieve at this difficult time."

Arthur and his twin brother Earl appeared in their father's 2014 docu-drama 20,000 Days On Earth.
