A restored and remixed version of John Lennon & Yoko Ono’s Imagine will reach theaters around the world beginning on Sept. 17.

The movie documents the making of the 1971 album Imagine and features never-before-seen footage.

According to a press release, Imagine, which Lennon and Ono directed, was restored frame-by-frame from the original reels, and the audio has been remixed by Paul Hicks. It guest stars Fred Astaire, Andy Warhol and Dick Cavett. The bonus footage, 15 minutes in all, includes Lennon and his band -- George Harrison, Nicky Hopkins, Klaus Voorman and Alan White -- recording his anti-Paul McCartney diatribe "How Do You Sleep?" and "Oh My Love." A special Dolby Atmos "raw studio" mix was created for these performances.

You can watch the new trailer below and get details on screening times, locations and tickets at the movie's website.

It's all part of a glut of media Ono is releasing to commemorate Imagine. On Oct. 9, what would have been Lennon's 78th birthday, she's publishing Imagine John Yoko, a 320-page book detailing the album's creation, complete with remembrances of more than 40 people who were close to the couple at the time. Eighty percent of the photos have never been published before.

“The people who all worked on Imagine were Peace People, and it was so enlightening and exciting all the way through to be one of them," Ono said. "Remember, each one of us has the power to change the world.”

Ono also has a new album, Warzone, arriving on Oct. 19. The record revisits 12 songs she recorded between 1970 and 2009, plus her own take on "Imagine." Last year, she was awarded a co-writing credit on the song based on a 1980 interview with Lennon, where he said the concept came from her book Grapefruit and that she was deserving of the credit.
