Director Peter Jackson may have won acclaim for his epic The Beatles Get Back documentary series but he says he would have "lost it" with the band if he had filmed the original 1970 Let It Be film himself.

Jackson, who also made the Lord of The Rings, worked with over sixty hours of footage filmed by Let It Be director Michael Lindsay-Hogg to make Get Back.

Speaking about first the film, which was shot in 1969 as The Beatles rehearsed and recorded songs that would end up on the Abbey Road and Let It Be albums, Jackson said of Lindsay-Hogg, "The poor guy was herding cats the whole time and I was just feeling so many times that I would have lost it!"

Jackson was taking part in a Q&A to promote the IMAX release of The Beatles: Get Back - The Rooftop Concert.

"I mean as much as I love the Beatles, I would have raised my voice at them a couple of times and read them the riot act because they would have driven me crazy, and Michael's just so calm." H added.

"I particularly enjoy seeing Michael twitch and squirm when things aren’t going quite his way; as a director I can sympathise with that and find it kind of funny.

"Some of my favourite bits in the rushes and the outtakes were Michael’s stuff because I don’t play in a band - I can love the Beatles and watch the Beatles like anyone - but crucially the person I was really relating to was Michael."

There are currently no plans for IMAX cinemas in Ireland to screen The Beatles: Get Back - The Rooftop Concert.
