NEW YORK -- The Tribeca Film Festival opened in a spirit of brotherly love -- both on the screen, and in thoughts for the people for Boston.
Richard Belzer began by dedicating this year's festival, the 12th annual, to Boston following Monday's deadly bombing at the Boston Marathon. Tribeca is no stranger to such horror: It was founded by Robert De Niro and Jane Rosenthal after the Sept. 11 terror attacks as a way to revitalize downtown Manhattan.
"Tonight, we're all Bostonians," said Belzer at the Tribeca Performing Arts Center.
Belzer, De Niro and Rosenthal introduced the festival's opening gala attraction, the documentary "Mistaken for Strangers." It was made by Tom Berninger, brother of the lead singer of the Brooklyn indie rock band the National, Matt Berninger.
Though an amateur filmmaker, Tom Berninger filmed his experience as a roadie on tour with his older brother's band. He called it "a small, little, lo-fi thing" in his brief remarks before the film played.
But the humble "Mistaken for Strangers" delighted the star-studded Tribeca crowd.
The film chronicles the siblings' relationship, particularly showing Tom Berninger as the uncertain, lesser-accomplished underdog between the two. It's less of a behind the scenes document than a quirky, oddly moving film about the making of a film.
Following the screening, the National performed at an after-party at the Highland Ballroom. It's not the first time Tribeca has begun with a concert and documentary pairing. In 2011, the festival opened with Elton John performing after Cameron Crowe's music documentary "The Union."
Tribeca runs through April 28.
