The director of “The Lord of the Rings” saga is taking on another epic topic for his latest documentary -- the legendary band The Beatles.

Peter Jackson is helming a new film that uses clips from 55 hours of never-before-released film of John Lennon, Paul McCartney, George Harrison and Ringo Starr, as they recorded their final album "Let it Be," NME reported.

There’s also 140 hours of audio being released.

The film was recorded from Jan. 2 through Jan. 31, 1969.

It also documents the band's last concert on the rooftop of Apple Records on Jan. 30, 1969. The film was announced on the 50th anniversary of the recording of that concert, Variety reported.

Jackson said in a statement that it is a project "that Beatles fans have long dreamt about," Variety reported.

“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,” Jackson said.

A release date or name for the documentary has not been released yet, but was done with full cooperation from McCartney, Starr, Yoko Ono and Olivia Harrison, NME reported.

And while the original film was shot on 15mm, Jackson is expected to use a similar technique to process the footage as he did for his World War I documentary "They Shall Never Grow Old," Variety reported.

The performance was a part of filming for a documentary of the band rehearsing and recording the album Let It Be. The 42 minute session drew crowds to the street & adjoining rooftops. This was the band's final live performance before breaking up in April 1970. Performing on the rooftop left to right: Ringo Starr, Paul McCartney, John Lennon and George Harrison.
