The distributor of climate change documentary An Inconvenient Truth is making a last-ditch effort to prolong the life of the movie on Hong Kong cinema screens. But with it reaping HK$1.86 million in ticket revenue for the first two weeks of screening since October 5, film industry insiders said it is already doing well despite netting far less than Hollywood commercial movies shown during the same period. The Departed, the Hollywood remake of Hong Kong hit Infernal Affairs, netted about HK$4.8 million in its first week in the same period, compared with HK$1.12 million for An Inconvenient Truth. The number of cinemas showing An Inconvenient Truth has fallen from 22 to 14, with most now screening it once or twice a day. 'We have tried everything we can to extend the screening. But some cinema operators are just too pragmatic,' said Regent Lai, local manager of Intercontinental Film Distributors. The distributor is seeking support from a few core cinemas to continue screenings as long as possible. Showing the film at the Space Museum was also explored but the screening venues were fully booked. Ms Lai said the turnout was satisfactory compared to other documentaries such as Fahrenheit 9/11. However, some moviegoers wrongly expected the film, fronted by former US vice-president Al Gore, to be like the Hollywood climate catastrophe movie The Day After Tomorrow. 'We've had Al Gore here and even the policy address had a few lines about climate change. Yet, it doesn't really help a film that fundamentally lacks entertainment and content for the masses,' Ms Lai said. She said the distributor was especially disappointed with the response from big companies. 'We had thought those big corporates would support the movie to build up their green image. But it wasn't the case.' While one major blue-chip company had bought 3,000 tickets for its staff and clients, some had refused because they feared being politically connected with Mr Gore. It is estimated that more than 50,000 people have watched the film in Hong Kong, including 7,000 students who had group screenings organised by their schools. Ms Lai said the movie would not be shown on the mainland as it did not have approval from the authorities. No pirated copies had been found so far.
