The film tradition of young women killers is long: from Natalie Portman in The Professional and Anne Parillaud and Bridget Fonda as Femme Nikita to Jennifer Garner in Alias and Chloe Moretz in Kick-Ass. Now we have a new entrant in the category: Saorise Ronan in Hanna (April 8), a Focus Features film that reunites the star with her director on Atonement, Joe Wright. The trailer is below. Eric Bana plays her father; Cate Blanchett co-stars.
