Watch: NOWHERE BOY movie trailer

The London film festival closes on Thursday with the world premiere of "Nowhere Boy," about John Lennon's rebellious teenage years and his torrid relationship with his aunt and mother before the Beatles were formed.

The directorial debut of video artist Sam Taylor-Wood, the movie stars Aaron Johnson as an angry, confused Lennon who struggles to understand why his mother Julia left him with his aunt Mimi when he was a small boy.
