Variety said that Mark Strong and Anne-Marie Duff will also star in the movie, directed by Brighton Rock's Rowan Joffe.
The film, based on British author SJ Watson's book of the same name, follows a woman with amnesia who uses a journal to rekindle her memories, but discovers terrifying new truths.

Colin and Nicole are also set to appear in wartime drama The Railway Man together, due for release this year.
