Acclaimed Japanese director Takeshi Kitano has shot a short film to mark this year's 60th Cannes Film Festival, his office said Wednesday, but he is keeping the content under wraps. Kitano, who is 60 himself, is one of 35 directors from 25 countries asked by Cannes organisers to contribute a film, three minutes or shorter, on the theme of a "motion-picture theatre" for the anniversary. Germany's Wim Wenders, Poland's Roman Polanski, Britain's Ken Loach, China's Zhang Yimou and Hong Kong's Wong Karwai are also lined up for the collection, to be screened at the festival on May 20.
