The Beatles were an English rock band formed in Liverpool in 1960. With a line-up comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr, they are commonly regarded as the most influential band of all time. Between 1964 and 1970, they appeared in five major motion pictures, beginning with A Hard Day's Night (1964) and ending with Let It Be (1970). From late 1965 to 1969, the group also appeared in several promotional films for their singles, which have been credited with anticipating music videos and the rise of MTV in the 1980s.

Sir Richard Starkey, known professionally as Ringo Starr, is an English musician, songwriter and actor who achieved international fame as the drummer for the Beatles. Starr occasionally sang lead vocals with the group, usually for one song on each album, including "Yellow Submarine" and "With a Little Help from My Friends". He also wrote and sang the Beatles songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of four others.
