Will Smith goes to war “against a corporation that owns a day of the week,” a.k.a. the National Football League, in the first trailer for Concussion, which debuted in Sports Illustrated writer Peter King’s Monday Morning Quarterback column on Monday.

Based on the true story of Dr. Bennet Omalu (Smith), a forensic neuropathologist who discovered chronic traumatic encephalopathy (or CTE) while performing an autopsy on former Pittsburgh Steelers center Mike Webster, who died by suicide in 2002, Concussion tackles one of the many controversies to befall football in recent years: the effect playing the game has on the human brain.

“I have no position on whether or not people should play football or whether they should have their kids play football,” director Peter Landesman told King. “To me, this is a story about making adult choices. Once you have the information—and the information has been obscured for a long time, it’s been buried and covered up by people who don’t want to damage the sport—the information is now out there and I hope this movie brings together the information in a way that the general public can metabolize and now make their own decisions. So now that you know that concussions can kill you and playing the sport can kill you, it’s on every parent and it’s on every college player, it’s on every high school player and professional player on whether you are going to let your child play.”

Also starring Gugu Mbatha-Raw, Alec Baldwin, Luke Wilson, Paul Reiser and Albert Brooks, Concussion is set for release on Christmas Day. Watch the film’s first trailer below.
