Scripted by Matt Greenhalgh and directed by first-time feature director Sam Taylor-Wood, the film focuses on Lennon’s late teen home life and early friendship with Paul McCartney. Kristen Scott Thomas plays Lennon’s conservative aunt, essentially his adoptive mother, and Anne-Marie Duff plays his less reliable birth mother. It’s coming of age stuff, and an invocation of the time period that led to the turbulent decade for which the Beatles were a soundtrack.
