BUENOS AIRES — The increasingly competitive world of Latin American film sales and distribution has gained another player: Mexico’s Vendo Cine.Making its international market debut at Ventana Sur, Vendo Cine is run by Estrella Araiza, a former acquisitions-sales executive at Guadalajara sales company Latinofusion, plus partner Arturo Perez Navarro. Early moves include the acquisition of North, Central and South American rights to Mexican helmer Bernardo Arellano’s “Between Night and Day,” a drama about an autistic man, which snagged San Sebastian’s 2010 Films in Progress award. Vendo will handle Mexican distribution directly on “Night,” its first release, teaming with the National Cinematheque of Mexico and local arthouse exhibitors for its Jan. 18 theatrical bow. Vendo also plans a small theatrical release in February of Chiapas-set docu feature “Ch’ulel,” helmed by Jorge Creuheras. As a sales agent, the Guadalajara-based company has acquired international rights to Natalia Beristain’s first feature, Venice’s Critics’ Week player “I Don’t Want to Sleep Alone,” which won the jury prize at November’s Morelia festival. “I have always believed that Mexico needs a sales agent that has a special focus on Mexico,” Araiza said at Ventana Sur. Vendo Cine will also “take films from the rest of Latin America, handling no more than eight a year,” Araiza added.
