It seems like Mr. Shyamalan is building his team very carefully. Starting with the casting of Will Smith and his son Jaden Smith for his project, After Earth first, and then casting Sophie Okonedo, Zoe Kravitz, and Isabelle Furhman. After Earth script was originally written by Gary Whitta ( Book of Eli), and then Shyamalan himself did some of the writing. After that screenwriter Stephen Ghagan (Traffic) and Mark Boal (The Hurt Locker) also did some polishing on the script respectively.
Now via twitter, Shyamalan just disclosed to the world that costumer designer Amy Westcott is going to be working with him on After Earth. Amy’s credit includes films like Black Swan, The Wrestler.
