First Round of Programming Announced for Tribeca Film Festival New features from Rachel Boynton, Laurie Collyer and Linda Bloodworth-Thomason are among the 46 works announced on Tuesday for the 2013 Tribeca Film Festival, which unveiled its selections for the competitive world narrative and documentary categories, as well as its noncompetitive Viewpoints series. "Big Men," written and directed by Ms. Boynton ("Our Brand Is Crisis"), will make its world premiere on April 18, the opening film of Tribeca's world documentary feature lineup. In a news release, "Big Men" was described as an "industrial exposé" for which Ms. Boynton "gained unprecedented access to Africa's oil companies" to produce "a gripping account of the costly personal tolls levied when American corporate interests pursue oil in places like Ghana and the Niger River Delta." The world narrative feature series will open on April 18 with "Bluebird," written and directed by Lance Edmands, and starring Amy Morton as a school-bus driver in a Maine logging town. The cast also includes Adam Driver, Margo Martindale and John Slattery. Other films competing in this category include "Sunlight Jr.," written and directed by Ms. Collyer ("Sherrybaby"), about a pregnant convenience-store worker and her paraplegic boyfriend. It stars Naomi Watts, Matt Dillon and Norman Reedus. The Viewpoints series will also begin on April 18, with "Flex Is Kings," a film about Brooklyn street performers and promoters directed by Deidre Schoo and Michael Nichols. This lineup also includes "Bridegroom," a documentary written and directed by Ms. Bloodworth-Thomason (the creator of television's "Designing Women") about a same-sex couple fighting for their legal rights. This year's Tribeca Film Festival will open on April 17 with the music documentary "Mistaken for Strangers" and will run through April 28.
