An actor who worked on The Beatles film Help! has unearthed some never-before-seen footage from the set.

According to The Guardian, the late actor, Leo McKern, captured the footage of the band during their downtime on set at an Austrian ski resort. The paper reports the footage “shows the Fab Four being very larky and giggly, pretending to play instruments in a brass band and messing around with their stunt doubles.”

The footage has been stored away for more than 50 years and was never released. McKern’s daughter, Abigail, went through the archives with book dealer and actor Neil Pearson to “help disperse her mother’s collection of children’s literature.”

McKern’s footage will be going on sale, with the Guardian listing the asking price at $45,000. Before it goes on sale, the footage will be shown on British television tonight (May 12th). Abigail McKern is scheduled to help present clips on the BBC program The One Show alongside Paul McCartney‘s stunt double and Eleanor Bron, who played a villainous high priestess in the movie.

“It is unseen footage of people who were, at that time, the most famous people on earth,” said Pearson. “It is footage of golden age Beatles, fooling around between takes, waiting for something to happen … I know that feeling.”
