Oasis rockers and sometimes bitter rivals Liam and Noel Gallagher were at the Venice Film Festival over the weekend for the debut of their new Hulu doc, “Oasis: Don’t Look Back In Anger” — and the screening, naturally, included profanity, a “mosh pit” and a Man City flag. 

The brash brothers attended a photo call (without incident) and were seen arriving by boat before they hit the red carpet for their film’s debut at the Palazzo del Cinema to throngs of screaming fans.

“Peaky Blinders” creator Steven Knight directed the film, which gets a theatrical release on Sept. 11. It will subsequently stream on Hulu and Disney+.

The film follows the band’s reunion tour, “Oasis Live ‘25,” with footage of the concerts, rehearsals and backstage action, plus interviews with the famed brothers.

The doc received an 8-minute standing ovation, and one fan even reportedly flew a Man City flag over the balcony at the event on Saturday night. The audience also sang along to “Champagne Supernova” and other tunes. 

In typical Gallagher fashion, when the brothers were on stage for the lengthy standing O, Liam seemed to ask, “Should we f–k off?” reports said, not knowing when the pair should make their exit. 

The Gallaghers then waded into the crowd and signed autographs, with Variety describing the scene as a veritable mosh pit.
