New York-based distribution company Grasshopper Film and Gratitude Films have jointly acquired U.S. distribution rights to Italian director Michelangelo Frammartino’s Venice Special Jury Prize winner “Il Buco,” about a group of speleologists who in 1961 discover Europe’s deepest cave.

The deal was negotiated by Ryan Krivoshey of Grasshopper Film with Nadine Rothschild of Paris and Berlin-based Coproduction Office on the eve of the U.S. premiere of “Il Buco” at the New York Film Festival. Gratitude, which is based in Los Angeles and Mumbai, is headed by Anu Rangachar, a producer and the former programmer for the Mumbai Film Festival.
