Hollywood actor Saoirse Ronan is all set to star as the lead in The Outrun, a film adaptation of Amy Liptrot's best-selling memoir of the same name.

The project has Nora Fingscheidt (of The Unforgivable-fame) on board as director. Fingscheidt and Liptrot are adapting the book for the screen.

The story follows Rona, a woman fresh out of rehab, who returns to Scotland's wild Orkney Islands and to the sheep farm of her childhood, after more than a decade away.

Ronan is best known for her roles in titles like Lady Bird and Little Women. Fingscheidt is best known for her critically acclaimed German feature System Crasher and English follow-up hit The Unforgivable.

Protagonist Pictures will introduce the project to buyers at Berlin's European Film Market next month. Sarah Brocklehurst's Brock Media will produce the film alongside Ronan, Jack Lowden and Dominic Norris under Arcade Pictures alongside Ignacio Salazar-Simpson and Ricardo Marco Bude of Mogambo.

Jonas Weydemann and Jakob D Weydemann of Germany's Weydemann Bros will co-produce together with BBC Film and Screen Scotland.
