The Beatles' animated classic Yellow Submarine has been digitally restored for a new DVD/Blu-Ray release.

The 1968 film, which has been out of print for years, will hit stores at the end of May.

Restoration expert Paul Rutan, Jr. and his team of specializts at Triage Motion Picture Services and Eque Inc. worked on the film for months, cleaning up the film's photochemical elements by hand, frame by frame.

The DVD and Blu-Ray packages will feature a making-of documentary, the film's original theatrical trailer, audio commentary by producer John Coates and art director Heinz Edelmann and interviews with others involved with the film.

To coincide with the re-release, Candlewick Press bosses will release a new, compact hardcover edition of the Yellow Submarine picture book in April. The reworked soundtrack will also hit stores.
