What do you get when you mix Greg Kinnear, Alan Alda, and windshield wipers up with a dollop of Dave Matthews Band? The trailer for the new movie "Flash of Genius." It's the true story of Robert Kearns, his family and their quest to get automakers to pay him for his invention, the intermittent windshield wiper. It looks like it'll be touching, poignant and oh yes, make the old fat cats who used to run U.S. automakers look like complete dolts for ignoring the rights of the inventor. We may even wipe away a tear. Full trailer after the jump.
