This film is absolutely excellent, especially in that it barely touches on The Beatles, spending most of its time telling John Lennon's very real story of growing up with a family torn apart. It came out late last year in Australia and England, long before Kickass was released, so I knew him more from this than from that. And that he's married the director of this.
