Olga Kurylenko and Andrea Riseborough have boarded Joseph Kosinski's untitled sci-fi pic as the female leads alongside Tom Cruise.

The film follows a futuristic soldier stationed on Earth, the surface of which has been destroyed by aliens. When he discovers a mysterious woman in a crash-landed pod, it sets off a chain of events that cause him to question everything he knows.

William Monahan and Karl Gajdusek previously wrote drafts of the script, which is currently being rewritten by Michael Arndt. Peter Chernin, Dylan Clark and Barry Levine will be producing with the director.

Jessica Chastain had to pass on the role to pursue Kathryn Bigelow's untitled Osama bin Laden. Olivia Wilde and Noomi Rapace also auditioned for the film back in November.

The project is still in early development.
