What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.
I sought Ben Affleck because I needed an everyman for this role. Ben appeals to men and women. He gives you a sense of intelligence the notion of a guy who can think on his feet.
