RING and WBC middleweight champion Sergio Martinez is the subject of a documentary entitled Maravilla that covers much of his career, starting from his days as an amateur through his victory over Julio Cesar Chavez Jr., according to his advisors, Nathan and Sampson Lewkowicz.

Directed by Juan Pablo Cadaveira, Maravilla will be screened four times next month among the 22 films in The Tribeca Film Festival's Viewpoints Section on April 19, 21, 23 and 26, according to Nathan Lewkowicz.

"It's up for an award for 'Best New Director.' I saw it probably about six months ago. It's definitely a great movie. For a first-time director to produce something like this, it's definitely amazing," said Lewkowicz.

"It details a very interesting story, which is the story of Sergio Martinez. He's a fighter who came from nothing and yet, he became one of the most popular athletes in boxing. It's definitely a rags-to-riches story."

The festival website offers this description of Maravilla:

"A true underdog story, Maravilla follows Argentinian boxer Sergio 'Maravilla' Martinez, as he sets out to reclaim the title of middleweight champion that was unfairly snatched from him in 2011 by Julio Chavez Jr.

"Focusing on the rise of Martinez from penniless amateur to world champion and sporting celebrity, director Juan Pablo Cadaveira offers a fascinating glimpse into today's boxing landscape, revealing the politics of the sporting profession that often places entertainment value over the sport itself. In English and Spanish with subtitles."

The veteran southpaw turned 39 in February and will defend his championships against Miguel Cotto on June 7 at New York's Madison Square Garden on HBO Pay Per View. Martinez met fellow Argentine Pope Francis at the Vatican in October, marking the first time a boxer met the leader of the Catholic Church since Muhammad Ali met Pope John Paul II in 1982.

Martinez (51-2-2, 28 knockouts), who is promoted by Lou DiBella, had to rise from the canvas during each of his last two unanimous-decision victories over Chavez and Martin Murray, while also having suffered injuries as a result of those bouts.

After the Chavez fight, during which he regained the WBC’s belt, Martinez received eight stitches to repair a cut over his left eye, two staples in his head and suffered from both a broken left hand and torn ligaments in his right knee, the latter of which required surgery to repair.

Martinez required a second surgery after having damaged the knee injury, later determined to be a torn right meniscus, during his April 2013 triumph over Murray.

Among Martinez’s other wins are a decision over Kelly Pavlik, a stoppage over current IBF 160-pound beltholder Darren Barker and knockouts of former titleholders Sergei Dzinziruk and Paul Williams.

Another world premiere to be featured at the Tribeca Film festival is the documentary Champs, which traces the careers of a few well-known boxers including Mike Tyson and Evander Holyfield, according to ArtsBeat.
