Due out October 4, How I Live Now is the big screen adaptation of the award-winning young adult novel by Meg Rosoff.

Directed by Kevin Macdonald (The Last King of Scotland, One Day In September), the apocalyptic drama sees Saoirse Ronan take on the role of American teenager Daisy, who is sent away for the summer to live with her aunt and cousins on their remote English countryside farm. Daisy's new surroundings are dashed by the outbreak of a 21st century world war, leaving her and her family isolated and forced to fend for themselves.
