Is the new movie called " Warrior" based on a true story?

The film Warrior from 2011, starring Tom Hardy as Tommy Conlon, Nick Nolte as Paddy Conlon, and Joel Edgerton as Brendan Conlon, is not based on a true story. The story of estranged brothers entering a mixed martial arts tournament was written by Gavin O'Connor, Anthony Tambakis, and Cliff Dorfman; O'Connor also directed the film and played J.J. Riley. Hardy gained 28 pounds for the role of Tommy, and kept the same physique to play Bane in The Dark Knight Rises.
