The Beatles in "Help!"

The Beatles' second feature film, 1965's "Help!," has its worldwide digital release exclusively on iTunes today. It's digitally restored with a 5.1 soundtrack, and includes a 30-minute documentary on the production, memories from the cast and crew, the restoration process, an outtake scene and more. The film's director, Richard Lester ("A Hard Day's Night"), gives an intro, plus an appreciation following by Martin Scorsese. Watch the original trailer below.

Classics songs in the film include "You're Going to Lose That Girl," "You've Got to Hide Your Love Away," "Ticket to Ride," "I Need You," "The Night Before," "Another Girl" and -- of course -- "Help!"

The debut of "Help!" on iTunes and Blu-ray follows 2012's "Yellow Submarine" and "Magical Mystery Tour" iTunes and Blu-ray releases.

Here's the madcap synopsis, in case you need a refresher:

Help! follows The Beatles as they become passive recipients of an outside plot that revolves around Ringo's possession of a sacrificial ring, which he cannot remove from his finger. As a result, he and his bandmates John, Paul and George are chased from London to the Austrian Alps and the Bahamas by religious cult members, a mad scientist and the London police.

In addition to starring The Beatles, Help! boasts a witty script, a great cast of British character actors, and classic Beatles songs.
