Factual error: During the Mike Webster autopsy, Dr Omalu asks Gracie for Mike's CT Scan of the brain again, but what she holds up is a MRI film, not CT. Then after interpreting the displayed MRI Dr. Omalu tells Gracie that this brain should be a mess, but it looks completely normal. Whereas the MRI shown by Gracie reveals several abnormalities like brain atrophy and degeneration due to complications of previous disease process. (00:27:45 - 00:28:30)
Factual error: We are briefly given a shot of Heinz Field, panning out to the Pittsburgh skyline. Next to the Heinz Field stadium screen, an "American Airlines" advertisement is shown. This advertisement uses the new American Airlines logo which was not adopted until early 2013. (00:37:35)
Factual error: When Dr. Omalu is talking with Mrs. Waters, we are briefly given a shot of her entertainment console. Next to Dr. Omalu's head you can see a Blu-Ray disc player. Since most of this film takes place in late 2002, this is impossible because the modern Blu-Ray format wasn't even released until mid 2006. (01:09:35)
