Capitol Records' lack of interest throughout 1963 had not gone unnoticed, and a competitor, United Artists Records, encouraged their film division to offer the group a three-motion-picture deal, primarily for the commercial potential of the soundtracks. Directed by Richard Lester, A Hard Day's Night involved the band for six weeks in March–April 1964 as they played themselves in a mock-documentary. The film premiered in London and New York in July and August, respectively, and as an international success, with some critics drawing comparison with the Marx Brothers. According to Erlewine, the accompanying soundtrack album, A Hard Day's Night, saw them "truly coming into their own as a band. All of the disparate influences on their first two albums had coalesced into a bright, joyous, original sound, filled with ringing guitars and irresistible melodies." That "ringing guitar" sound was primarily the product of Harrison's 12-string electric Rickenbacker, a prototype given to him by the manufacturer, which made its debut on the record. During the week of 4 April 1964, the Beatles held twelve positions on the Billboard Hot 100 singles chart, including the top five. Their popularity generated unprecedented interest in British music, and a number of other UK acts subsequently made their own American debuts, successfully touring over the next three years in what was termed the British Invasion.

Touring internationally in June and July, the Beatles staged 37 shows over 27 days in Denmark, the Netherlands, Hong Kong, Australia and New Zealand. In August they returned to the US, with a 30-concert tour of 23 cities. Generating intense interest once again, the month-long tour attracted between 10,000 and 20,000 fans to each 30-minute performance in cities from San Francisco to New York.
