Metro: “Hands of Stone” isn’t a hagiography; it’s not even a movie that straightens a record. It’s closer to a yes-man who tells their boss their speech was great, ignoring the part where his pants fell down. The subject is Roberto Duran, one of the greatest boxers who’s never scored a movie. You think he’d deserve one: He pulled himself up from the bootstraps of Panama’s streets to hold world titles in four different weight classes. He had a punch so hard he earned the eponymous nickname. But here’s the rub: In the seventh round of a highly-publicized rematch with Sugar Ray Leonard in 1980, he abruptly called it off, taking his toys and leaving with the whole world watching.
