Any time Hollywood makes a film based on a true story, the casting tells all. Filmmakers signal who the heroes and villains are when they choose the actors for each role. In the film Concussion, it's clear the Dream Factory has put its finger in the breeze and is poised to crack-block the National Football League.

The movie is the damn-near-unbelievable-but-true story of how Dr. Bennet Omalu discovered that chronic traumatic encephalopathy (CTE) is caused by playing tackle football.

Smith has been nominated for best actor Oscars for playing a sainted version of Muhammad Ali (Ali/The Greatest) and a homeless father who achieves success by never giving up on his dreams (The Pursuit of Happyness). Smith is highly conscious of his role-model image, which is why he turned down the part of Django, the ex-slave in Quentin Tarantino's Django Unchained.

It is a bittersweet tale of an underdog's partial triumph--like Rocky, except that the film opposes sports-induced brain injuries instead of celebrating them. The film works as entertainment. It works as politics. And it works as an audience-stirring indictment. All in all, that's dangerous news for the National Football League.

Thanks to Omalu's real-life battle, we now know that CTE is a neurological disorder that results from repeated blows to the frontal lobe of the brain. It is widely believed that CTE...
