The trailer for the Sinéad O'Connor documentary Nothing Compares has been released ahead of the film's arrival in cinemas next month.
The feature directorial debut of Belfast filmmaker Kathryn Ferguson, Nothing Compares opens on Friday October 7.
Releasing the trailer, film studio Paramount said: "Directed by Kathryn Ferguson (Taking the Waters, Space to Be), Nothing Compares charts Sinéad OʼConnor's phenomenal rise to worldwide fame and examines how she used her voice at the height of her stardom, before her iconoclastic personality led to her exile from the pop mainstream.
"Focusing on O'Connor's prophetic words and deeds from 1987 to 1993, the film presents an authoritative, richly cinematic portrait of this fearless artist through a contemporary feminist lens."
Nothing Compares was an official selection in the World Cinema Documentary Competition at the Sundance Film Festival in the US earlier this year.
It has won numerous awards including Best Irish Documentary at the Galway Film Fleadh, the Audience Award for Best Documentary at the Aegean Film Festival, and the Audience Award at Docs Ireland.
