Based on a true story, Concussion is about Bennet I. Omalu, M.D, a forensic neuropathology doctor who discovered Chronic traumatic encephalopathy, a progressive degenerative disease that is caused by traumatic brain injuries such as multiple concussions. As of now it can only be diagnosed after death. After doing an autopsy on former Pittsburgh Steelers center Mike Webster, Dr. Omalu uncovered CTE. Will Smith brings Dr. Omalu’s story to the big screen on Christmas Day. Even with an all star cast I doubt the NFL is going to be okay with this movie being released.
