Synopsis: Greg Kinnear stars in a man against the system docudrama Flash of Genius as inventor Robert Kearns, the visionary who developed the modern intermittent windshield wiper. Kearns submitted the invention to each of the big three auto companies, each of which promptly rejected it; the companies then turned around and put the device to use. The enraged inventor spent several decades attempting to collect on his patent, and mounting lawsuits that traveled all the way to the Supreme Court. Dermot Mulroney plays Kinnear’s best friend, with Lauren Graham rounding out the supporting cast.
