The Beatles
Magical Mystery Tour and Yellow Submarine

Two Beatles film projects were conceived within weeks of completing Sgt. Pepper: Magical Mystery Tour, a one-hour television film, and Yellow Submarine, an animated feature-length film produced by United Artists. The group began recording music for the former in late April 1967, but the project then lay dormant as they focused on recording songs for the latter. On 25 June, the Beatles performed their forthcoming single " All You Need Is Love " to an estimated 350 million viewers on Our World, the first live global television link. Released a week later, during the Summer of Love, the song was adopted as a flower power anthem. The Beatles' use of psychedelic drugs was at its height during that summer. In July and August, the group pursued interests related to similar utopian-based ideology, including a week-long investigation into the possibility of starting an island-based commune off the coast of Greece.

On 24 August, the group were introduced to Maharishi Mahesh Yogi in London. The next day, they travelled to Bangor for his Transcendental Meditation retreat. On 27 August, their manager's assistant, Peter Brown, phoned to inform them that Epstein had died. The coroner ruled the death an accidental carbitol overdose, although it was widely rumoured to be a suicide. His death left the group disoriented and fearful about the future. Lennon recalled: "We collapsed. I knew that we were in trouble then. I didn't really have any misconceptions about our ability to do anything other than play music, and I was scared. I thought, 'We've fuckin' had it now. ' " Harrison's then-wife Pattie Boyd remembered that "Paul and George were in complete shock. I don't think it could have been worse if they had heard that their own fathers had dropped dead." During a band meeting in September, McCartney recommended that the band proceed with Magical Mystery Tour.

The Magical Mystery Tour soundtrack was released in the UK as a six-track double extended play (EP) in early December 1967. It was the first example of a double EP in the UK. The record carried on the psychedelic vein of Sgt. Pepper, though in line with the band's wishes, the packaging reinforced the idea that the release was a film soundtrack rather than a follow-up to Sgt. Pepper. In the US, the soundtrack appeared as an identically titled LP that also included five tracks from the band's recent singles. In its first three weeks, the album set a record for the highest initial sales of any Capitol LP, and it is the only Capitol compilation later to be adopted in the band's official canon of studio albums.

Magical Mystery Tour first aired on Boxing Day to an audience of approximately 15 million. Largely directed by McCartney, the film was the band's first critical failure in the UK. It was dismissed as "blatant rubbish" by the Daily Express; the Daily Mail called it "a colossal conceit"; and The Guardian labelled the film "a kind of fantasy morality play about the grossness and warmth and stupidity of the audience". Gould describes it as "a great deal of raw footage showing a group of people getting on, getting off, and riding on a bus". Although the viewership figures were respectable, its slating in the press led US television networks to lose interest in broadcasting the film.

The group were less involved with Yellow Submarine, which featured the band appearing as themselves for only a short live-action segment. Premiering in July 1968, the film featured cartoon versions of the band members and a soundtrack with eleven of their songs, including four unreleased studio recordings that made their debut in the film. Critics praised the film for its music, humour and innovative visual style. A soundtrack LP was issued seven months later; it contained those four new songs, the title track (already issued on Revolver), "All You Need Is Love" (already issued as a single and on the US Magical Mystery Tour LP) and seven instrumental pieces composed by Martin.
