Concussion is a 2015 American biographical sports drama film directed and written by Peter Landesman. The movie stars Will Smith as Dr. Bennet Omalu, a Nigerian-born forensic neuropathologist who discovered Chronic Traumatic Encephalopathy (CTE) in the brains of several deceased football players.
The film explores Omalu's struggle to fight against the National Football League (NFL) and the medical community, who initially dismiss his findings and attempt to discredit his work. As Omalu continues his investigation and brings more evidence of CTE to light, he faces threats, intimidation, and even the possibility of losing his job.
The story centers around Omalu's determination to reveal the truth about CTE and its devastating effects on the players' brains, despite the consequences he faces. The film also touches on the issue of greed and the power held by large institutions over the lives of their employees.
Concussion received positive reviews for its strong performances, especially from Smith, and its thought-provoking storyline. The movie sheds light on the dangers of sports-related head injuries and the importance of advocating for the truth.
