The Beatles' 1968 animated movie Yellow Submarine will return to cinemas across Ireland this summer to mark its fiftieth anniversary.

The audio, which features Beatles songs like A Day in the Life and Lucy in the Sky with Diamonds was remixed in 5.1 stereo sound at Abbey Road Studios, where the Beatles recorded most of their work.

The movie’s mind-bending psychedelic landscapes - in which the Beatles tried to wipe out the so-called Blue Meanies - have been restored in 4k digital resolution. The animation was actually cleaned up by hand, frame by frame, rather than through automated digital software.

Budgetary disputes bedeviled the making of the movie. "There was an epic struggle between the British and the American producers about money," says Valentine Edelmann, daughter of Czech-German graphic designer Heinz Edelmann who was in charge of animation.  

"The British studio told the American producers that they needed more to finish it," says Edelmann. "But the Americans refused to move from the budget."

According to her version, director Charles Dunning and the animators reportedly `stole' the only copy, placed it in Dunning's bank vault and told the Americans they could have it back, if they were prepared to pay. They were eventually provided with some more cash input and the final budget came in at £250,000.

Interestingly, Liverpudlian poet Roger McGough was brought in to lend a more authentic voice to the script after Erich Segal, author of the Love Story novel had spent some time on the project as part of a team collaboration.

The movie can be seen in selected cinemas in Ireland on July 8, including Dublin and Galway. See facebook.com/yellowsubmarinethefilm
