Edgar Ramírez stars as Panamanian boxing champion Roberto Durán in Hands of Stone. The biographical drama, which debuted in Cannes last May is directed by Jonathan Jakubowicz based on the book by Christian Giudice. Robert De Niro plays Ray Arcel, the legendary trainer who coached Durán through his Welterweight rivalry with Sugar Ray Leonard. We asked the Venezuelan Golden Globe nominee (Carlos, 2011) what it was like to act with “Raging Bull” in his corner.
