It took four months to digitally restore the Beatles' 'Yellow Submarine', but that's only one-sixth the time it took to create it. The animated feature film will be re-released on DVD and Blu-ray on May 28. Each frame was attended to individually, instead of by using the more common automated software process.

The Associated Press reports that the film's soundtrack -- featuring songs like 'Lucy in the Sky With Diamonds and 'Eleanor Rigby' -- will be reissued the same day. It's a package that will introduce the late '60s album to a new generation of fans, while providing a pleasant psychedelic flashback to those who lived it.

“As a fan of animation and as a film-maker, I tip my hat to the artists of ‘Yellow Submarine’, whose revolutionary work helped pave the way for the fantastically diverse world of animation that we all enjoy today,” Pixar studios chief John Lasseter says in the sleeve notes for the re-release.

Billboard reports the new DVD will include bonus materials like a making-of documentary, the original trailer, interviews and behind the scenes footage. Lasseter also has a 16-page essay.

This is a big year for 'Yellow Submarine.' On April 24, Candlewick Press will release a hardcover picture book which combines the film's script with original artwork.
