First Look: Saoirse Ronan is a Killing Machine in ‘Hanna’ (Trailer)

New trailer shows the “Atonement” star wielding all manner of weaponry and causing loads of mayhem

While this is a departure. 

Joe Wright's, the director best known for stiff upper lip dramas such as "Pride & Prejudice" and "Atonement," is returning with an action heavy spy drama "Hanna." 

The film reunites him with his "Atonement" star Saoirse Ronan, but in this go-round she plays a teenage killing machine, not an aspiring novelist. Cate Blanchett and Eric Bana co-star. 

Based on the trailer released Tuesday, there will be lots and lots of blood. 

"Hanna" hits theaters on April 8, 2011.
