In a film that dives into the NFL's handling of concussions, Will Smith plays Omalu a neuropathologist who discovers a specific form of brain trauma . The latest trailer for 'Concussion' is all pain and drama as Omalu faces the seemingly impossible task of having his work acknowledged by the NFL. Executives in the sports world are all blind eyes and deaf ears, claiming that the doctor's science comes "from nowhere."
Omalu's research centers on the sudden death of football Hall-of-Famer Mike Webster. Webster had dementia before his death in 2002, as well as repeated head injuries during his time as a professional football player.
