Few screenwriters share Stephen Gaghan’s pedigree. He won the Oscar for penning Steven Soderbergh’sin 2000, then earned a well-deserved nomination for writing the 2005 political drama, which he also directed. So if a studio felt the need to hireto rewrite a script for M. Night Shyamalan to helm, Gaghan’s an excellent choice.According to Variety , he’ll polish a draft of Gary Whitta’sbefore Shyamalan begins shooting . Thedirector reportedly tinkered with Whitta’s draft, but Sony Pictures and Overbrook have brought Gaghan on board to give the draft another pass. I guess they sawAnd that’s the thing about Shyamalan. He’s a competent filmmaker who is decent with special effects and can muster tension in suspenseful situations, but his scripts leave a lot to be desired. As Variety notes, he has been the lone screenwriter credited on his nine feature films, and they’ve predominantly gone down in quality since he broke on the scene within 1999.Shyamalan reportedly will begin filmingin February, with Will and Jaden Smith playing a father-son team who crash onto our planet 1,000 years after mankind has abandoned it. The crash, according to reports, injures the elder astronaut, sending the younger traveler on a difficult journey to find help on this isolated Earth. It sounds like it could mix Smith’swith Shyamalan’s. There’s potential here. Let’s hope Gaghan can flesh it out.
