Full synopsis reads:
In After Earth, one thousand years after cataclysmic events forced humanity's escape from Earth, Nova Prime has become mankind's new home. Legendary General Cypher Raige (played by Will Smith) returns from an extended tour of duty to his estranged family, ready to be a father to his 13-year-old son, Kitai (played by Jaden Smith). When an asteroid storm damages Cypher and Kitai's craft, they crash-land on a now unfamiliar and dangerous Earth. As his father lies dying in the cockpit, Kitai must trek across the hostile terrain to recover their rescue beacon. His whole life, Kitai has wanted nothing more than to be a soldier like his father. Today, he gets his chance.
Zoe Kravitz and Sophie Okonedo co-star as sister/daughter and mother/wife respectively.
Stephen Gaghan (Traffic, Syriana) was brought on to polish up Shaymalan's script before shooting began (a very good idea IMHO), and Columbia Pictures is shooting for a June 7th summer 2013 release.
Trailer #2 dropped last night, which I was thoroughly underwhelmed by; here's the new poster:
