Before Will Smith saves the day as Deadshot in next year’s Suicide Squad, he plays forensic neuropathologist Dr. Bennet Omalu in Concussion – a film based on the September 2009 GQ article, Game Brain by Jeanne Laskas.

Dr. Bennet famously (or infamously) made the first CTE (Chronic Traumatic Encephalopathy) discover in the brains of NFL players. The discovery lead to a Bennet challenging the NFL, their doctors, and everything we thought we knew about concussions. Ultimately his findings lead to the concussion protocols the NFL and NCAA have adopted in recent years.

Do I want to hear Will Smith using an accent for two hours? No. Do I want to see Will Smith in a thriller? Yes! Do I want to see Will Smith do some good crying and angry finger pointing? Hell yes!!!!!

I’m sure NFL isn’t too happy about this movie making them look like boogeymen. They’re probably even less happy it opens in December, right before their playoffs start.

Concussion also stars Adewale Akinnuoye-Agbaje, Alec Baldwin, Gugu Mbatha-Raw, Eddie Marsan, Luke Wilson, Albert Brooks, and Richard T. Jones.

Concussion opens December 25th.
