Most of The Beatles most successful songs from their movies came from three soundtracks.It didn’t take long for The Beatles to go multimedia. As Beatlemania took over the world, they added movies to their output with A Hard Day’s Night and Help! in 1964 and 1965, respectively. They were on top of the world; even the songs they abandoned turned into hits. The Beatles kept writing songs to soundtrack their movies, and these were the seven most successful.
The Fab Four made hay in the relatively short time they were together. Between 1963 and 1970, there wasn’t a year where they didn’t release at least one album. Add in hundreds of live shows, scores of interviews, television appearances, and recording hit non-album singles, and it’s a wonder they didn’t keel over from exhaustion.
With that kind of schedule, The Beatles might have preferred built-in time to blow off steam on their movies. Seeing the evolution of their films was quite remarkable.
