Jodie Foster will direct “Sugar Kings,” and likely star in the Tribeca Films-produced drama for Universal Pictures. “Sugar” is about a young lawyer who teams with a veteran public-interest attorney to take on powerful sugar barons who are exploiting cane-cutting migrant workers. The movie was hatched by Tribeca in 2001 when Universal bought the rights to Marie Brenner’s Vanity Fair investigative article “In the Kingdom of Big Sugar.” The article focuses on Alfy and Pepe Fanjul, who owned a sugar-manufacturing empire in Florida. The magnates were hounded by attorney Edward Tuddenham, who charged that the brothers treated 20,000 sugar-cane cutters like slave labor, hiding behind their well-developed political connections and social standing.
