Nowhere Boy is a 2009 British biographical drama film, directed by Sam Taylor-Johnson in her directorial debut. Written by Matt Greenhalgh, it is based on Julia Baird's biography of her half-brother, the musician John Lennon. Nowhere Boy is about the teenage years of Lennon (Aaron Taylor-Johnson), his relationships with his aunt Mimi Smith (Kristin Scott Thomas) and his mother Julia Lennon (Anne-Marie Duff), the creation of his first band, the Quarrymen, and its evolution into the Beatles.

Following its premiere at the London Film Festival on 29 October 2009, Nowhere Boy opened in British theatres on 26 December 2009. Nearly a year later, in October 2010, the film received its US release, coinciding with the 70th anniversary of Lennon's birth. Nowhere Boy received positive reviews from critics and was a moderate hit at the box office, earning £4.3 million on a £1.2 million budget.
