MADRID — Spain’s Fernando Trueba P.C. has boarded helmer-scribe Victoria Galardi’s “I Thought It Was a Party,” a high-profile Argentine title being brought onto the international market.Starring Elena Anaya (“The Skin I Live In,”) and Valeria Bertuccelli (“A Boyfriend for My Wife”), the dramedy is distributed in Argentina by UIP. Galardi’s Gale Cine produces with Nathalia Videla Pena and Juan Pablo Gugliotta’s Magma Cine in Buenos Aires, and Fernando Trueba P.C., run by Oscar-winning director Fernando Trueba (“Belle Epoque”) and his partner Cristina Huete. Producers are Huete, Galardi and Videla Pena. “Party” rolls Nov. 26 in and around Buenos Aires. Argentina’s Incaa Film Institute and Argentine private-sector investors, including Cindy Teperman, are also backing “Party,” one of the first projects to go into production after presentation at the San Sebastian Film Festival’s Europe-Latin America Co-production Forum in September. “Party” is a step-up for a young Argentine director fast emerging onto the international scene. It comes days after Pablo Trapero inked to direct “Six Suspects” for Working Title and Magma unveiled Pablo Fendrik’s “The Ardor,” with Gael Garcia Bernal and Alice Braga. Galardi said “Party” will bear comparison to her earlier pics in its “comic tone, acting, my interest for characters more than issues, and stories showing something of human stupidity, jealousy, weaknesses and complexity.” “I liked the screenplay a lot, above all, how she tells a story, her look, her characters,” Huete added. Producers are in conversations with sales agents and aim to advance a deal in early December at Argentina’s Ventana Sur mart.
