I'm a geophysicist and all my earth science books when I was a student, I had to give the wrong answer to get an A. We used to ridicule continental drift. It was something we laughed at. We learned of Marshall Kay's geosynclinal cycle, which is a bunch of crap.
Every time a director calls me and says, 'If you practice a lot in two months, can you be an American?' And I always tell them, 'Well, maybe but I'm French. So it's going to be hard to be someone else.'
