Concussion–the movie about athletes who sustain concussions during play–presents one of the hottest health topics in sports circles to its viewers. With Hollywood on board with this topic, the film might do as much good as doctors have in spreading the word about the dangers involved.

Premiering on Christmas Day, Concussion stars Will Smith as Nigerian-born forensic pathologist Dr. Bennet Omalu. He is the doctor who discovered a disorder similar to Alzheimer’s–called Chronic Traumatic Encephalopathy, or CTE–while doing an autopsy on a former NFL player. He then went on a crusade to make the public aware of the dangers of football-related head injuries.

Since Dr. Omalu’s research began more than 10 years ago, the public has learned a lot about these sports-related blows to the head.

Former NFL quarterback Brett Favre spoke to CBS This Morning about his injuries and the memory loss he sustained as a result.

“This was a little shocking to me that I couldn’t remember my daughter playing youth soccer,” Favre said.

A concussion is a mild traumatic brain injury, typically caused by a blow or jolt to the head.

Concussion, the movie, proves football is dangerous and makes one wonder if it’s really a sport, according to the Huffington Post.

The publication’s review of Concussion says the movie’s end credits will “stir up anger and a discussion about the validity of football as a sport. Dr. Omalu fought for the truth to be admitted by the NFL, then dropped the ball. Concussion only tells part of the story.”

Between the serious nature of this film and Will Smith as its lead character, do you think Concussion is worth a trip to the movie theater?

It definitely sounds like one all coaches and parents of kids who play sports–especially football or hockey–should plan to see.
