The Beady Eye frontman explained that he would prefer to start the film off with his high profile falling out with brother Noel Gallagher in Paris, which eventually led to the band's demise.
"Sometimes, when we've had a few drinks, we sit about telling stories and talk about putting them in an Oasis film. I'd be up for that," he said, according to The Sun.
He added: "But I'd start it with Paris. I wouldn't want it to end on such a bummer. I'd start at the end and work my way backwards.
"It'd be a long film but it'd be a film worth watching, believe me. It'd be a funny film and all."
Liam Gallagher is currently working on his first movie The Longest Cocktail Party with his company 1 Productions. The project will focus on The Beatles' late publicist Derek Taylor.
He recently said that his brother Noel is not as good as a solo artist without him.
