King Kong director Peter Jackson has added a documentary film about the plight of gorillas to the DVD release of the Hollywood blockbuster, in a bid to prevent the extinction of the endangered species. The acclaimed film-maker is teaming up with the International Gorilla Conservation Programme for the environmental campaign, after the original 1933 Kong movie prompted a huge upsurge in gorilla hunting. The DVD release of the remake - due to hit stores later this year - is hoped to increase public awareness of the species, which is predicted to be extinct within thirty years. [More]
