Concussion - Official Trailer (2015) - Will Smith

Sony Pictures Entertainment decided to make a movie focusing on the death and dementia professional football players have endured from repeated hits to the head, in spite of the N.F.L.’s efforts toward a cover-up. Will Smith is to star as one of the first scientists to disclose the problem. It named the film bluntly, “Concussion."
