Robert De Niro and Edgar Ramirez have signed on for 'Hands of Stone'.

The actors will star in the upcoming biopic about champion boxer Roberto Duran, with Ramirez set to play the legendary sportsman and De Niro in the role of his trainer, Ray Arcel, reports Deadline.

Duran was among the world's elite boxers during his heyday, winning 103 of his 119 fights, and had many well-remembered bouts with fellow boxing legend Sugar Ray Leonard, including one infamous match in which the boxer gave up midway through the fight, crying, 'No mas.'

The film - which is expected to focus on the relationship between Duran and his trainer - is written and directed by Jonathan Jakubowicz, who will also produce alongside Jay Weisleder of La Piedra Films. Duran will also contribute to the film as an associate producer.

Weisleder said: "The story of Roberto Duran and Ray Arcel is not only a homage to the golden days of boxing; it is most importantly the story of a fatherless man who teaches every single one of us the true meaning of never giving up."

Jakubowicz added: "The infamous 'No mas' fight is the biggest enigma in the history of boxing. This movie will answer the enigma, with the best talent any director can possibly dream."

Filming is due to begin in Panama in September.
