Hanna (2011)

Here’s a fairytale the Grimm Brothers dare not have imagined: A 16-year-old girl, raised in full isolation and trained to be a ruthless assassin by her golden knight father, is set out onto the world to exact revenge against the wicked witch who killed mommy. “Hanna” is not that bluntly supernatural, though. Daddy (Eric Bana) is an ex-CIA agent who we think is nutty paranoid until we learn he is rightfully so. The Wicked Witch (Cate Blanchett) is his CIA boss, a soulless Texan obsessed with material goods. Yes, it’s a commentary. Director Joe Wright is clearly having fun by squashing logic and ending his taut thriller at a derelict amusement park, with Blanchett walking out of the mouth of the Big Bad Wolf. This would all be laughable were it not for Saoirse Ronan, who ruled over Wright’s “Atonement.” As Hanna, she effortlessly bounces from a teen with no memory of women, and no idea of TV or music or cars, to a killer on a dime. She’s a better heroine than the girl from “Twilight.” Very “Never Let Me Go, Jason Bourne.” B
