We based loosely based Harrison Ford on him because I've known him for a long time when shrinking so I heard support as Parkinson's and so he believed you know I was never a very spiritual person I just didn't grow up that way but they believe in this thing called the field. He said now if you're not spiritual you can just believe that you're acutely aware of it for the first time in your life  and noticing it the same way that you suddenly notice pregnant people everywhere.
