Joe Wright won our hearts with his past films Pride and Prejudice and Atonement. But his next film unleashes his violent side, via neck-snapping bioengineered teen assassin Hanna, played by Saoirse Ronan. Watch as she goes on a slaughtering spree in this new international trailer.

Synopsis:

Hanna (Saoirse Ronan) is a teenage girl. Uniquely, she has the strength, the stamina, and the smarts of a solider; these come from being raised by her father (Eric Bana), an ex-CIA man, in the wilds of Sweden. Living a life unlike any other teenager, her upbringing and training have been one and the same, all geared to making her the perfect assassin. The turning point in her adolescence is a sharp one; sent into the world by her father on a mission, Hanna journeys stealthily across Europe while eluding agents dispatched after her by a ruthless intelligence operative with secrets of her own (Cate Blanchett). As she nears her ultimate target, Hanna faces startling revelations about her existence and unexpected questions about her humanity.

Hanna, which is scored by the Chemical Brothers, will be out on April 8th, 2011.
