Sony Pictures Classics has picked up all North American rights to the feel-good Russian/French movie “Window to Paris,” screening here in the Panorama section of the 44th Berlinale.The “Window” deal is thought to be the first U.S. distribution deal completed at this year’s Berlin film market. “Window to Paris” is directed by little-known Russian helmer Jurij Mamin and stars French actress Agnes Soral. It is a fantasy comedy about the adventures of two friends in St. Petersburg who discover that a hidden window at the top of their apartment house leads magically onto a roof in Paris. Sony Pictures Classics co-president Marcie Bloom described the film, which is largely in Russian, as “incredibly good-hearted, a very sweet comedy with the romantic naivete and entertainment value that marks films like ‘Belle Epoque,’ ‘Wedding Banquet’ and ‘Like Water for Chocolate.’ “ Produced by Sarl The pic was produced by Fontaine Sarl in St. Petersburg with co-production coin from Paris-based sales agent Sodaperaga and La Sept Cinema. Sodaperaga is handling worldwide distribution and has also signed deals at Berlin with Mikado in Italy, Films de l’Atalante in France and NewVision Films in Australia. Bloom said she had not heard of the film or its director before coming to Berlin. “No matter how much research you do, you’re hoping to discover things that from your perspective come out of nowhere. Many of the films at Berlin are frankly quite heavy, so when you see a film that’s clearly such a crowd-pleaser, you’re especially impressed,” she said.
