Liam Gallagher says the Oasis documentary is so good it will give audiences "multiple orgasms".
The film - directed by Matt Whitecross - charts the rock band's incredible journey from a council estate in Manchester to global success, culminating in their two historic concerts at Knebworth in August 1996 which were witnessed by a total of 250,000 fans.
Liam says anyone who watches the film will be left in a state of ecstasy, especially if they are fans of his former group.
Speaking at a screening of 'Supersonic' at the Vue Cinema in London on Sunday night (03.10.16), he told BANG Showbiz: "I think anyone who watches it will know about Oasis, no one's going to come away and be like, 'Wow, f***ing hell.' They know what it is, I'm sure people will enjoy it if they're into the band, I'm sure some people will f***ing hate it. There's lots in it, but if you know Oasis and you're into that kind of thing you're going to have multiple orgasms ... Oasis were what we were, we were great and we were s**t at the same time. It was an emotional ride man, I think that it was rocking."
Liam, 44, and his estranged brother Noel, 49, gave hours of interviews for the project talking about all of the on stage and backstage antics of the 'Wonderwall' hitmakers - who split in 2009.
The singer admits he was shocked by how much footage there was of the band's early days because back in the 90s no one was walking around with a camera phone in their pocket to capture their antics.
He said: "There was a lot that I didn't remember, the bits that I didn't know were filmed I was like, F***ing hell!' I was pretty surprised that there was that much footage because back in them days we didn't have camera phones and all that, you know what I mean."
Although he enjoyed looking back at the early years of Oasis, Liam insists he doesn't get nostalgic for those times because every moment of his life is glorious.
The 'Songbird' songwriter said: "I did enjoy looking back at it. But I think life is glorious, every day is a f***ing glory day, whether you're making music or picking flowers. But yeah I enjoyed looking back at the band, it was incredible."
Liam was joined at the screening by his girlfriend Debbie Gwyther and his sons Gene and Lennon - whose mothers are his ex-wives Nicole Appleton and Patsy Kensit.
After attending the London event, the 'Rock 'n' Roll Star' singer and Debbie flew by helicopter to attend the film's premiere in Manchester.
