When Noel and Liam Gallagher announced the Oasis reunion after 15 years of public feuds, insults traded in interviews, and endless battles across social media, many people — including the band’s own fans — doubted it would ever actually happen. And yet, it did. More than that, Oasis’ return became one of the biggest cultural and musical events of the decade, bringing together not only the fans who grew up in the 1990s, but also an entire generation that discovered the band long after its breakup.

The first teaser for Don’t Look Back in Anger, the documentary set to premiere in IMAX theaters this September before arriving on Disney+, takes a predictable but understandable approach: it leans into the tension of reconciliation. The trailer revisits the traumatic 2009 split, with Liam admitting that “the way everything ended was unacceptable,” while Noel questions whether he could ever share a stage with his brother again. The suspense it builds is straightforward: could they really overcome fifteen years of resentment?

The problem is that we already know the answer.

We know because we watched the tour happen. We know because we saw Liam and Noel not only sharing stages around the world, but also learning how to exist together again as a family. If money was indeed the primary motivation behind the reunion — as many have suspected and neither brother has ever tried very hard to deny — somehow, it ended up working better than anyone could have imagined. Today, the image of the brothers laughing, emotional, and spending time together again may be the biggest surprise of this entire story.

Personally, I probably wouldn’t have leaned so heavily into the mystery of that first rehearsal or the question of whether the reunion would actually work. The real fascination of this story was never “Will they do it?” but rather “How did they do it?” After all, we’re talking about two men who spent a decade and a half turning family grievances into public spectacle and who, unexpectedly, discovered that the music they created together was still bigger than their resentment.

And that is precisely where Don’t Look Back in Anger becomes truly compelling.

Produced by Steven Knight (Peaky Blinders) and directed by Dylan Southern and Will Lovelace, the documentary promises unprecedented access to rehearsals, backstage moments, and, perhaps most importantly, Noel and Liam’s first joint interview in more than two decades. More than documenting a sold-out world tour or a triumphant comeback, the film appears interested in something even rarer: the reconstruction of a relationship that once seemed beyond repair.

Perhaps that is why the title remains so perfect. Don’t Look Back in Anger has always been a song about moving forward without becoming trapped by the past — ironically, a philosophy Noel Gallagher himself has championed since the 1990s. Nearly forty years after Oasis was formed, the Gallagher brothers may have finally decided to follow their own advice.

And after waiting fifteen years for this moment, the truth is that all of us now want to know exactly how it happened.
