Universal Pictures has finally settled on Jessica Chastain to play one of the female leads in Horizons. We reported last month Jessica Chastain was one of five finalists, along with Olivia Wilde, Brit Marling, Noomi Rapace and Olga Kurylenko.

The story is set in a world where the Earth has become too toxic for humans, with society moving to cities built above the clouds. Tom Cruise plays one of the last men on Earth, a repair man who discovers a mysterious woman has crash landed on the planet. They both set off on a journey that causes them to question everything they know about Earth.

The two female lead roles are the mysterious woman and Tom Cruise's wife. It isn't known which of these roles Jessica Chastain is in talks for. It is also believed that one of the other actresses mentioned may land the other female lead.

Joseph Kosinski is directing Horizons from a script by Karl Gajdusek and William Monahan. Joseph Kosinski created the graphic novel which the project is based on. Production is scheduled to begin this winter, with a July 19, 2013 release date already set by Universal.
