Quentin Tarantino, Keanu Reeves, Uma Thurman and Salma Hayek have expressed interest in joining the 30th anniversary Hong Kong International Film Festival in April - if it has Asia's largest outdoor screenings at the Tamar site. Festival organisers have invited the Hollywood stars to attend, but bureaucrats have been less forthcoming than the superstars. After more than six months of negotiations, they still haven't given festival organisers permission. The Lands Department, which oversees the site's tenancy, rejected the festival's initial application in August without giving reasons. The Post has learned the department suggested the festival reapply as the screenings had not been ruled out. Organisers subsequently lodged two applications last month but they have had no reply. 'They kept telling us to wait,' programme manager Beatrice Chan Ka-wai said. 'But we have to take the booking folder to the printers this week. If they had said no earlier, we would've looked for other locations.' A government spokeswoman said: 'We are still considering their application.' The festival said details of the stars' attendance were yet to be finalised. But some stars, such as Thurman and Reeves, might cancel if outdoor screenings could not take place, as their films have been scheduled for outdoor sessions. 'We will have a tribute to action choreographers this year and part of it will be held outdoors,' said festival director Peter Tsi Ka-kei. 'Keanu Reeves, Uma Thurman and especially Quentin Tarantino have special associations with Hong Kong kung fu movies.' Ms Chan said: 'Outdoor screenings are a major attraction to these Hollywood stars. If there's no outdoor screening, they might not come, as screenings at theatres mean nothing to them. We also have to get back to them as soon as possible to fit schedules.' This year's outdoor screenings were expected to entertain at least 20,000 people. More than 16,000 attended the screenings last year. It is not the first time the government has held up event organisers' requests for the Tamar site. Last year organisers of Christmas rock marathon Wild Day Out applied for permission more than six months beforehand. They received approval just two days before the show, after selling all the tickets and setting up the stage.
