Cannes, France — A new feature-length documentary about former Oasis frontman Liam Gallagher's years in the musical wilderness is to be shown at the Cannes film festival, its producers said Tuesday.

"Liam Gallagher: As it Was" will be released next month to coincide with his second solo album, which is expected to hit the shelves soon.

Co-director Charlie Lightening and his crew began followed the British singer -- whose gift for making headlines is nearly as prodigious as his musical talent -- just before his comeback.

Gallagher's first solo album, "As It Was", was a hit in 2017 and Lightening told British music magazine NME that his new record is "gonna blow people away".

In a trailer for the film, which is showing at the Cannes market, Liam blames his brother Noel for the break-up of the Manchester band.

Oasis -- once billed as the biggest British band since The Beatles -- imploded in 2009 after Liam threw a plum at his older sibling.

The bickering brothers have still not buried the hatchet a decade after their famous final falling out, with Liam regularly taking swipes at his until now more successful sibling on social media.

"Liam is one of the most influential and accomplished musicians of the last 30 years," Seth Needle of distributors Screen Media told Variety, adding that the film "showcases his talent and personality like nothing before."

Lightening previously directed projects about Paul McCartney and British singer Jamiroquai. His co-director Gavin Fitzgerald made "Conor McGregor: Notorious" about the Irish mixed martial arts star as well as "The Fighting Irish" documentary on MMA fighters. — AFP
