A new documentary, "Oasis: Don't Look Back In Anger", premiered at the Venice Film Festival, chronicling brothers Noel and Liam Gallagher's decision to reunite Oasis for a heavily promoted, hugely oversubscribed world stadium tour, despite the acrimonious split that saw the band implode moments before a 2009 festival appearance. Directed by Dylan Southern and Will Lovelace, the film blends concert footage with an insider's look at the fraught reunion process, offering fans a rare glimpse behind the scenes of one of British music's most anticipated comebacks, though it stops short of explaining exactly why the brothers chose to bury the hatchet.

The film traces Oasis's peak in 1996-97 and argues their enduring appeal rests largely on two albums, 1994's "Definitely Maybe" and its follow-up "(What's the Story) Morning Glory?", despite the band having released seven records overall. It captures tense early rehearsal scenes, including Noel's doubts over whether Liam would even turn up, and highlights the return of guitarist Paul "Bonehead" Arthurs, absent since 1999, whose sound the band had reportedly missed. The reunion tour's opening Cardiff gig is portrayed as a triumph, drawing a surprisingly youthful crowd for a band marking three decades since their debut.
