Watch Will Smith Take on the NFL in Trailer for 'Concussion'

By Published on .

Less than two weeks before the official start of the NFL season, Sony Pictures has released the first trailer for the "Concussion," a movie starring Will Smith that addresses the issue of concussions in the league.

"Concussion" is based on "Game Brain," a 2009 story in GQ. Mr. Smith plays the real-life forensic neuropathologist Dr. Bennet Omalu, who discovered chronic traumatic encephalopathy (CTE), a disease of the brain that is linked to repeated brain trauma -- such as that endured by pro football players.

The use of the hashtag #ForTheGame implies that the moviemakers have nothing against the NFL, or football at the very least. But glimpses of the film suggest that NFL officials are going to come off a lot like Big Tobacco did in movies like "The Insider."

"Concussion," which is directed by Peter Landsman also stars Alec Baldwin, Luke Wilson, Albert Brooks and Gugu Mbatha-Raw.
