The Beatles and Lord of the Rings director Peter Jackson are collaborating on a new movie about the sessions the band underwent to record their final album.

Announced on Wednesday, the as-yet untitled documentary is based on 55 hours of unreleased footage of the Beatles in studio, which was shot 50 years ago, as they recorded ‘Let It Be’. A release date is not yet known.

The announcement comes on the 50th anniversary of the rooftop concert where John Lennon, Paul McCartney, George Harrison and Ringo Starr performed together public for the last time.

Peter Jackson said the new film would capture ‘the ultimate fly on the wall’ experience that Beatles fans have long dreamt about.

Jackson suggested the acrimony captured in the 1970 film was just one version of the story. “I was relieved to discover the reality is very different to the myth,” the “Lord of the Rings” director said. “After reviewing all the footage and audio that Michael Lindsay-Hogg shot 18 months before they broke up, 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.”

The new film is currently in production and has the full co-operation of McCartney, Starr, Yoko Ono Lennon and Olivia Harrison.
