Ten days before the NFL begins its season, the trailer for Will Smith’s next movie, Concussion, has hit the Internet. Smith plays Dr. Bennet Omalu, the person who discovered Chronic Traumatic Encephelopathy, or CTE, the neuro-degenerative disease caused by repeated head trauma, in the brains of two professional football players.

Omalu faced roadblocks from the NFL as he tried to reveal the damage the game could do to its players. Alec Baldwin stars alongside Smith as a doctor helping Omalu to bring his research to light.

The film is based on a 2009 article that ran in GQ called “Game Brain.”
