Jake Gyllenhaal was clearly living in the gym while preparing for his fictional role as Junior Middleweight champ Billy "The Great" Hope for Southpaw directed by Antoine Fuqua (Training Day), and his hard work pays off in the intense new trailer.
The movie, opening July 31, follows Billy Hope as he fights his way to a championship belt only to lose everything.
Rachel McAdams stars as Billy's caring wife Maureen, who is gunned down in front of him by another fighter wanting a shot at Billy's belt. Maureen's death sends Billy into a self-destructive, drug-addled spiral that leads the courts to take away his only daughter (Oona Laurence). Making matters worse, Billy's income gets cut off after a doping scandal forces officials to suspend his boxing license for a year.
Left with nothing, Billy turns to former boxer Titus "Tick" Wills (Forest Whitaker) to rebuild him into the champ he once was and defeat the man responsible for his wife's death.
"I'm going to fight again and I'm going to get my kid back," Gyllenhaal says in the trailer.
The movie also features Curtis "50 Cent" Jackson and Rita Ora, and by the looks of the trailer, it could be the best boxing movie in years. Check it out above.
