Here is the press announcement for the project:

THE BEATLES - New "GET BACK" film directed by Peter Jackson to be on Disney+ in November, 2021*

We are proud to announce an exciting new collaboration between The Beatles and the acclaimed Academy Award winning director Sir Peter Jackson
The new film will be based around 55 hours of never-released footage of The Beatles in the studio, shot between January 2nd and January 31st, 1969. These studio sessions produced The Beatles’ Grammy Award winning album Let It Be, with its Academy Award winning title song. The album was eventually released 18 months later in May 1970, several months after the band had broken up.

The filming was originally intended for a planned TV special, but organically turned into something completely different, climaxing with The Beatles’ legendary performance on the roof of Apple’s Savile Row London office — which took place exactly 50 years ago today.

Peter Jackson said, "The 55 hours of never-before-seen footage and 140 hours of audio made available to us, ensures this movie will be the ultimate ‘fly on the wall’ experience that Beatles fans have long dreamt about."

“I was relieved to discover the reality is very different to the myth,” continues Jackson, “it’s simply an amazing historical treasure-trove. Sure, there’s moments of drama - but none of the discord this project has long been associated with. Watching John, Paul, George, and Ringo work together, creating now-classic songs from scratch, is not only fascinating - it’s funny, uplifting and surprisingly intimate”.

"I’m thrilled and honoured to have been entrusted with this remarkable footage - making the movie will be a sheer joy.”
