Saoirse Ronan has reportedly become the latest addition to Ryan Gosling's directorial debut, How To Catch A Monster.
The Irish actress has apparently signed on for a role in the dark fantasy tale, reported Screen Daily.
Christina Hendricks is already on board to play a single mother-of-two, who is transported into a macabre and dark fantasy underworld when her teenage son discovers a secret road leading to an underwater town.
Production on How To Catch A Monster is expected to begin in Detroit in the spring.
Saoirse, last seen in Joe Wright's Hanna, has a number of movies out shortly including Andrew Niccol's big-screen adaptation of Stephenie Meyer's The Host, Neil Jordan's Byzantium and Kevin Macdonald's film version of Meg Rosoff's teen novel How I Live Now.
