Coach Roberto Mancini, in a suit rather than the blue and white striped scarf that became his trademark last season, was among the City staff and celebrities walking along the 'blue carpet' on Thursday for the opening of Blue Moon Rising.
The documentary-style film follows five obsessive fans during last season, City's first full season after the takeover that made it the world's richest club. It also features interviews with players, Mancini and City-mad musician Noel Gallagher.
"City's ambitions are huge," Nick London, one of the producers, told Reuters while a couple of big screens showed trailers of the film to the fans waiting outside the central Manchester cinema.
"The club has been transformed over the last few years and they thought they wanted to make a movie to begin with. And, as a producer, I can only applaud that.
"Eventually it will end up on DVD but the intention is initially that it gets a theatrical release in Manchester and elsewhere, goes on to DVD and maybe goes on to TV later on."
"Hopefully it'll be more drama, maybe with winning a competition or getting even higher in the league," said winger Adam Johnson.
"I haven't got a clue what I'd call the sequel."
