How 'Concussion' role 'enlightened' Will Smith

Talking about his role in the new flick 'Concussion,' Will Smith has revealed that it enlightened him about the dangerous effects of multiple concussions.

The 2015 movie revolves around the true story of Dr. Bennet Omalu who stumbled upon an insidious brain disorder affecting football players that began in 2002 with an autopsy on former Pittsburgh Steelers center Mike Webster, Channel 24 reported.

The 47-year-old actor added that when he met Omalu and went through the science, he was terrified as a parent as his son played football for four years and he had no idea this was an issue.

However, after researching the role and learning more about the condition, the "Focus' star remains a football fan and feels different about the game.

Smith added that he wanted to be a part of it just to deliver information to parents and to players because if he didn't know, he felt a lot of other people didn't know.
