6. Harry Potter and the Deathly Hallows: Part 2Year released: 2011 Overall U.S. box office gross: $381 million Like Star-Wars, the Harry Potter film series was a beloved piece of childhood fiction that likely stretched on longer than it had to. Also like Star Wars, by the time the last installment came around, it was clearly time to go. How much had all the students of Hogwarts grown since the first film was released in 2001? A year after playing the namesake wizardry school student in 2011, Daniel Radcliffe was cast as a troubled father in 2012's The Woman In Black.Part 2 was a fond farewell, but it was a tougher, scruffier last look at childhood for some than for others.
