Will Smith told Vanity Fair that he's surprised his film "Concussion" didn't have a bigger impact. He said, "I knew it would be hard because people love the game, but the science is so overwhelming, and it?s something that we really need to take a look at." The film focused on head-trauma in the NFL. It was released on Christmas Day in 2015. Smith received praise from critics for his portrayal of forensic pathologist Bennet Omalu and earned a Golden Globe nomination for the role.
