Since the soundtrack rights to Beatles songs are expensive, we may never see a John Lennon biopic focused on the most creative and interesting period of his life. Instead, we got 1994’s Backbeat (about Lennon’s friendship with Stuart Sutcliffe and his days in Hamburg), and now Nowhere Boy, the Weinsteins’ new movie about his childhood, with special emphasis on his relationships with his real mother and adoptive aunt (Kristin Scott Thomas) and the formation of the Quarrymen. That star Aaron Johnson looks almost nothing like Lennon is made less of a problem by the fact that the too-skinny Thomas Sangster looks even less like Paul McCartney. It’s pretty standard musical biopic material, but we like Scott Thomas, so maybe this won’t be so bad.
