Mat Whitecross, the award-winning director of the new Oasis documentary Supersonic, confesses he got a littled star struck when he met the Gallagher brothers for the first time.

“I don’t normally get star struck,” he says. “But meeting Noel and Liam for the first time was different for me. I grew up with them as these larger than life, almost mythological characters. But in person, they both put you at ease immediately; they’re incredibly down to earth and hilarious. They’re very good at holding court, so you can just sit back and enjoy the banter.

“The only obstacle we encountered really was trying to schedule Bonehead and Liam for different days, because we knew if they went out on the piss, we wouldn’t resurface for a week. We failed miserably on that front!”

Featuring extensive unseen archive footage, Oasis: Supersonic – which is out on DVD in November – charts the meteoric rise of the iconic Brit pop band, from the council estates of Manchester to their triumphant Knebworth concert in 1996.

A Supersonic trip with Oasis

Although the film boasts a wealth of new interviews, the film is constructed constructed solely from archive footage, with contemporary voices to tell the story. “Noel didn’t fancy watching middle-aged rockers talking about the good old days, and for me the voice-over approach definitely helped keep things feeling in the moment,” Whitecross says. “We also knew it was unlikely Noel and Liam would want to do their interviews together, but with voice-over, the viewer would feel they were having a conversation.”

The British filmmaker – whose credits include music videos from artist such as Coldplay and Jay-Z and the music dramas Sex&Drugs&Rock&Roll and Spike Island –also hopes the movie will inspire a new generation of musicians to follow the maverick spirit of Oasis .

“We live in a more corporate, manufactured world now,” he says. “Lunatic visionary chancers like Alan McGee have been squeezed out of the system. I think Noel in particular wanted this film to serve as a rallying cry in some way to the next generation of bands.

“His attitude is, if we did it – a bunch of shit kickers from a council estate – then you can too. Don’t let the music industry limit your horizons. I hope new bands see this film and remember a different way of doing things. Maybe a little bit of the spirit of Oasis can spark something in a new group of misfits, and they’ll go out and change the world again…”
