Russell Crowe (aka Fathead) stars as a mathematician suffering from paranoid schizophrenia; As this is very loosely based on a real person, we follow the character through school, into the world of teaching and government cryptography, marriage, sinking into madness and then slowly climbing out. It is primarily set in the Cold War era. I have never been a Russell Crowe fan, so you should read elsewhere for impressions of his performance. Personally, I quickly tired of his mumbling. Also, I am not fond of very long movies, and this is a very long movie. Director Howard has a few surprises in store that will engage the minds of 12 year old viewers everywhere. Jen Connelley is the nutty professor's wife, and Ed Harris plays a shadowy government figure.
