Robert De Niro's new boxing film "Hands Of Stone" has been added to this year's Cannes Film Festival lineup, in tribute to the iconic actor. Written and directed by Jonathan Jakubowicz, the boxing drama stars Édgar Ramirez as Roberto Duran, the Panamanian boxer who made his debut at 16-years-old in 1968 and did not retire until age 50 in 2002.
