Focus Features holds worldwide rights to the movie.
"We're so pleased to reunite with Saoirse and Joe for 'Hanna,' Focus' biggest production yet. With Saoirse taking on such a demanding role opposite Cate and Eric, this movie will be not only breathlessly exciting but also emotionally affecting," Focus Chief Executive Officer James Schamus said in a statement.
Ronan and Wright previously collaborated together on "Atonement."
"Hanna 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, an ex-CIA man, in the wilds of Sweden," Focus said in a synopsis of the film.
"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. As she nears her ultimate target, Hanna faces startling revelations about her existence and unexpected questions about her humanity."
