King Kong (2005)
Peter Jackson's enormous silverback from Skull Island/Pop Culture
In Peter Jackson's 2005 King Kong, the giant ape stands approximately 7.6 meters (25 feet) tall, making him considerably larger than any real gorilla but more grounded than some other cinematic Kongs. Weta Digital modeled Kong as a silverback gorilla scaled up, with an arm span of roughly 18 meters and an estimated mass of about 8,000 kg. Despite his size, Kong was animated with extraordinarily nuanced facial expressions captured from Andy Serkis's performance.
