"Concussion" is a movie starring Will Smith who plays Dr. Bennet Omalu, a Nigerian born forensic pathologist who discovered the degenerative disease called chronic traumatic encephalopathy or CTE, in football players.

Omalu was working in Pittsburgh when former Steelers center Mike Webster was brought into the coroner's office. He felt that something about the athlete's death just didn't seem right, so he investigated. That's when he made his discovery.

CTE can lead to memory loss, aggression and depression, and over the years, several NFL players diagnosed with CTE have killed themselves. But even though Omalu discovered this prevalent and life-ruining issue, the NFL was and has been resistant to his recognizing his discoveries.

"Concussion" is a movie about Omalu's journey, and is written and directed by Peter Landesman, a former college football player, who later became an investigative journalist and later turned his talents to filmmaking.

This is his third film he's written, with all of his work based on real life stories.
