StudioCanal has secured UK theatrical distribution rights to the comedy film, with production due to start on January 7 next year under the direction of Declan Lowney (Father Ted).
Partridge said of his big screen debut: "I'm simultaneously gladdened and pleased to see a British film being co-funded by the French dudes at StudioCanal. This is without doubt the greatest Anglo-French co-operation since the Normandy landings. This time, the heroes aren't Allied servicemen - they're motion picture financiers, who are equally brave.
"I'd also like to add that 'canal' - or, in English, 'canal' - is a transportation system close to my heart. In the late 18th century, this new method of logistics halved the price of coal in many English cities. If StudioCanal's investment can achieve even a fraction of that, I will be delighted."
Steve Coogan will return to play the North Norfolk Digital broadcaster. The actor also worked on the script with Armando Iannucci, Peter Baynham and Neil and Rob Gibbons.

In a recent interview with the Radio Times, Neil Gibbons said the story will see Partridge go up against a media conglomerate.
"North Norfolk Digital is bought by one of those big media companies that try to homogenise the output so you get very vanilla, corporate radio," he said. "For all Alan's faults, and much as he'd probably like to be, he's not very corporate. But that's just the starting point."
Rob added of the film's setting: "What we should have done is write in some glamorous locations, but we've put together a film where we won't leave East Anglia. Our fault. Not too late to rewrite, though..."
The Alan Partridge Movie will sit in a release slot that proved successful for TV-to-screen adaptation The Inbetweeners last year. The big-screen spin on E4's teen sitcom debuted on August 17 and grossed more than £40 million at the UK box office.
Partridge made his long-awaited TV comeback last night (June 25) on Sky Atlantic with one-hour special Welcome to the Places of My Life. The channel will broadcast Alan Partridge: Open Books with Martin Bryce next Monday (July 2) at 9pm.
