LOS ANGELES: Hollywood star Will Smith takes an unusual U-turn in his acting career by appearing in sports medical drama Concussion, which narrates the struggle of Nigerian doctor Bennet Omalu.

Smith, who plays the lead role, said he was interested to see the reaction of the real Omalu after the movie, reported Variety.

“It’s less about football and it’s more about the power and the necessity for the truth’, Smith said of the film.

Doctor Omalu suffered heavily in his pursuit of the truth. “For me, more than anything I’m a football dad. I love football. This is about informing parents and about delivering the truth and people will decide what they want to do with that,” he said.

Concussion, directed by Peter Landesman, also stars Gugu Mbatha-Raw, Luke Wilson and Alec Baldwin, and it’s due to be released on February 12.
