CANNES — New York’s downtown film scene descended on the rooftop of the Sofitel Friday for the premiere party for Ethan Hawke’s digital ensemble piece “Chelsea Walls,” which opened the Directors Fortnight. Hawke, nattily attired in a sequined shirt, was matched in fashion annals by wife Uma Thurman. Thurman, who appears in the film, poured herself into a pair of see-through lace flares that had admirers agog. Thurman said that unlike Hawke, Jennifer Jason Leigh and other thesps trying digital projects, she had no desire to direct unless she found “an amazing story.”

Also sporting an elaborate blazer was Quentin Tarantino, in town to toast producer Lawrence Bender’s Cannes award. When asked if he planned his own digital project, Tarantino said, “I have my own 35mm camera, I don’t need to.”

Also admiring the stunning view of the port and quaffing champagne were IFC’s Jonathan Sehring, an exec producer on the pic, digital guru Peter Broderick, producers’ rep Jeff Dowd, Lions Gate’s Tom Ortenberg and Marc Urman and co-producer Christine Vachon.
