French aerial photographer Yann Arthus-Bertrand (you may have seen his image of the heart-shaped vegetal formation in Grande Terre, New Caledonia) has brought his love of the Earth as seen from above to a whole new level. Editing from 500 hours of footage shot at more than 120 locations around the world from a helicopter, Arthus-Bertrand has put together a feature-length documentary looking at our Home (TVB Pearl; Friday at 8.30pm). A long-time environmentalist, Arthus-Bertrand names two main reasons for such an ambitious project: to record the beauty of Earth as we know it and to remind people that we are responsible for preventing the destruction of our only home. Denis Carot, the producer of the film, says: 'Although there is a general trend in our societies towards an awareness of ecological issues, concrete action is still too little, too slow - which constitutes in some ways the creed of the movie: it's too late to be a pessimist.' With funding from business conglomerate PPR (chief executive Francois-Henri Pinault is married to actress Salma Hayek) and distribution support from Luc Besson (The Big Blue) and his film company, Elzevir, it is hoped Home will be seen by millions around the world - and, for the most part, for free. This Friday, World Environment Day, the film will be released simultaneously in more than 50 countries, on every popular format: in cinemas and on cut-price DVD, television and the internet, and, for those lucky enough to be in Paris at 10pm, at a free screening beneath the Eiffel Tower. For the Hong Kong premiere, TVB Pearl will simulcast in English, narrated by actress Glenn Close, and Cantonese, narrated by our very own Stephen Chow Sing-chi.
