We don't know how Saoirse Ronan does it. 

The Irish actress has been out on the most chaotic press tour ever for Brooklyn (seriously she's been everywhere), is nominated for an Oscar and has another two movies coming out in 2016. 

And yet, the Carlow native still has time to plot her next film role.

Saoirse has just revealed that she will be starring in another adaptation of an Ian McEwan novel, her first being 2007's uber-successful Atonement. 

At just 13, Saoirse was Oscar-nominated for her turn in the film and the project single handedly propelled her career into the stratosphere. 

The 21-year-old will star in an adaptation of McEwan's 2007 Booker Prize nominated novella, On Chesil Beach. 

The moving story documents the honeymoon of a young couple who struggle to come to terms with their varying backgrounds, fears and issues with intimacy. 

"It's an extremely exciting prospect to be reunited with Saoirse Ronan on such a beautiful and heartbreaking project," said producers Elizabeth Karlsen and Stephen Woolley, who worked with the actress on the 2012 Neil Jordan film, Byzantium. 

The film is set to be helmed by theatre director Dominic Cooke and to begin filming later this Spring.
