Short answers, pulled from the story.
An eastern cult gathers on a beach to sacrifice a woman to their goddess Kaili because Ringo Starr has the sacrificial ring sent to him by the intended victim. The chief priest Clang and several cult members leave for London to retrieve the ring and sacrifice the girl after failed attempts to steal it without Ringo noticing.
Shooting commenced in the Bahamas on the 23rd of February 1965. Filming finished on the 14th of April at Ailsa Avenue in Twickenham.
The original title Eight Arms to Hold You was announced as the official title in mid-March 1965 but the press announced the retitle by mid-April 1965. Help! was settled on as the film's title later in April after neither Lennon nor McCartney were able to compose a good title song from its previous name.
Director Richard Lester received a larger budget for this film than he had for A Hard Day's Night thanks to the commercial success of the latter feature. Thus this feature film was in colour and shot on several overseas locations including London, Salisbury Plain, the Austrian Alps, New Providence Island and Paradise Island in the Bahamas.
The seven main songs formed the first side of the British release of the Help! album while the second side consisted of other new Beatles songs recorded at the same time or shortly afterwards. The US album released by Capitol Records includes the seven film tracks along with instrumental soundtrack songs orchestrated by Ken Thorne.
