Cate Blanchett has been tipped to join the assassin drama Hanna, says Deadline Hollywood.

Saoirse Ronan stars as a 14-year-old girl who has grown up entirely in a remote woods where her father has taught her to become a lethal assassin.

She soon leaves the woods for the first time and sets out on a job to kill a high-ranking government official with many secrets.

Eric Bana also stars.
