Levy started work on Bananaz when the band was formed in 2000, documenting the creation of the band's animated alter-egos, sales of more than 15m albums, and nominations for six Grammy awards, as well as unusual live gigs where musicians played behind a curtain. Levy shot more than 260 hours of footage over the six years.
Bananaz is currently in the final stages of editing, and the project has a running time around 90 minutes.
'It's more a documentary about musicians, it's been prepared in a way so that it comes across as a feature film, and isn't just for Gorillaz fans,' Levy told Screen International. 'There's no talking heads. There are stories, it's not just two blokes in a studio.'
Levy thinks the project will travel well internationally. 'Gorillaz are well known worldwide,' he said. 'This is also a film about two people working on one idea and seeing that idea come to life.'
Levy, a longtime friend of Albarn, previously worked on Blur's 1994 film Starshaped as well as BBC television documentaries and music videos.
Levy produced as well, with Slingshot's Rachel Connors.
HanWay's AFM slate also includes Battle For Haditha, Franklyn, The Red Baron and Genova.
