John Lennon, renowned musical icon and member of The Beatles, also made several forays into the world of cinema, although he never embarked on a true acting career. His roles often saw him portraying himself or stylized versions of himself.

His most significant films include "A Hard Day's Night" (1964) and "Help!" (1965), both directed by Richard Lester. In these films, Lennon displayed a natural charisma and an effortless spontaneity, contributing to the success of the musical comedies which cemented The Beatles' playful and rebellious image.

A notable exception was his brief role in "How I Won the War" (1967), also directed by Lester, where he portrayed Private Gripweed. Here he delivered a performance more akin to traditional acting, showcasing a surprising comedic streak and a remarkable screen presence, despite his lack of formal acting training. His style was characterized by authenticity and magnetism, rather than by formal technique.
