Nicole Kidman is in talks to star in Before I Go to Sleep, reports Screen Daily. Director Rowan Joffe (who wrote 2010's The American and 28 Weeks Later) is writing the adaptation based on S.J. Watson's best-selling novel about a woman who wakes up every morning without any memories from the last twenty years, and then tries to piece together her memory and identity with the help of her journal, her mysterious neurologist, and her husband, whom she's not sure she can trust. Memento? 50 First Dates? Who can say?
