Forty-six of the 89 feature-length films slated for the 2013 Tribeca Film Festival were announced, including the world premieres for the documentary, narrative and viewpoints selections, TheWrap said.

The festival, founded by Robert De Niro, Jane Rosenthal and Craig Hatkoff after 9/11 to help revitalize the lower Manhattan neighborhood, runs April 17 to 28.

The documentary "Mistaken for Strangers" will make its world premiere on opening night. The film follows the Brooklyn-based band the National on tour and is directed by Tom Berninger, brother of lead singer Matt Berninger. The opening screening will be followed by a performance by the National.

“Big Men,” the Brad Pitt-produced African oil industry documentary written and directed by Rachel Boynton, opens the world documentary section. The narrative selection competition kicks off with “Bluebird” (pictured below right) starring Amy Morton, which director Lance Edmands gives a small Maine logging town the butterfly-effect treatment.

And “Flex Is Kings,” directed Deidre Schoo and Michael Nichols, opens the viewpoints section with a film about the Brooklyn street dance performance called "flexing."

All three films will premiere on April 18.
