The stars will still turn up and the movie line-up looks good but the tone of the Cannes film festival will be more black and white than technicolor in 2009. The credit crunch means Hollywood studios are tightening their belts and conspicuous consumption is temporarily out of fashion. Deal-making will go on but is likely to be more circumspect. “You can feel people are more conservative, more selective,” said Helen Lee Kim, president of Mandate International. “They are being more careful and not taking those big jumps as they might have last year.” The annual celebration of cinema in the south of France, famed for its wild beach parties, giant yachts and red carpets, opens on Wednesday with the premiere of “Up”, an animated comedy from Disney that underlines the growing importance of 3D. Each day, two competition films are screened to critics and journalists before their red carpet premieres in the Grand Theater Lumiere, while directors and stars juggle interview schedules and photo calls. Hundreds more movies are shown outside the main competition, many of them on the bustling market which is a less visible, yet vital part of Cannes' status as the world's top film festival. On the plus side, Hollywood studios are enjoying a bumper box office in 2009 despite the global recession, and the dollar's relative strength will boost purchasing power. But the protracted credit crunch, added to slowing DVD sales and depressed advertising, will cast a shadow over Cannes, both in terms of business and pleasure. Vanity Fair magazine, which last year held one of the festival's glitziest parties, is not coming to Cannes while demand for luxury yachts at the harbor has been slow. “Normally we're very busy during the festival, but all the corporate clients, the Americans, have reduced their budgets terribly and we're getting very little demand from companies,” said Philippe Trombetta, who runs Class Yacht Charter, a luxury yacht-chartering business in Cannes.
