Collider: I noticed in the credits last night that Will Smith came up with the idea for the film. How did all this germinate?
Gary Whitta: Yes, totally legit. I think this is actually the first movie that Will has a story credit on. I wasnt on any of his other movies, but to me, it feels like [theres more] of his DNA in this that any movie hes ever made. It was his original idea, he had a little one-page premise; not a lot of meat on the bones, but it was his original idea, and they wanted a writer to help him develop it. So they sent me the little logline and I went away and built the world out a little bit and pitched it to him. We developed it together, and then I went away and wrote the script. So the way the writing credits broke down, I think, is actually totally representativestory by Will Smith, and [director M. Night Shyamalan] and I wrote the screenplay together.
