Martinez doc to premiere April 19

While middleweight champ Sergio Martinez is getting ready for his huge fight with star Miguel Cotto on June 7 (HBO PPV) at New York's Madison Square Garden, he is also awaiting the release of the outstanding documentary "Maravilla" about him and his career.

The film's world premiere will come April 19 at the prestigious Tribeca Film Festival in New York, but ESPN.com exclusively has the trailer for the film. "Maravilla" is one of 22 films in the festival's "viewpoints section."

Director Juan Cadaveira, who followed Martinez for a few years, had behind-the-scenes access to Martinez, including for negotiations, the political chaos that caused him to be stripped of his belts (including an epic meltdown by promoter Lou DiBella at the WBC convention), the build-up to his much-anticipated showdown with Julio Cesar Chavez Jr. in 2012 and an examination of the vulnerable physical condition of an aging champion.

In the interest of full disclosure, I am in the film. Cadaveira approached me to be in it a couple of years ago and I sat for a lengthy interview with him in at The Wynn in Las Vegas. I was not paid to participate.

The Tribeca Film Festival's website describes the documentary as "a true underdog story. 'Maravilla' follows Argentinean 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."
