Tarzan, released in 1999, is the 37th film in the Disney Animated Canon. Based on Edgar Rice Burroughs Tarzan series, it stars Tony Goldwyn as the eponymous hero, Minnie Driver as his Love Interest Jane, and BRIAN BLESSED as the antagonist, Clayton.
The film opens in the late 1880s, with a couple and their infant son ending up in Darkest Africa after a shipwreck. Later, Kala, a gorilla whose infant son was killed by a leopard, Sabor, hears a baby cry in an abandoned treehouse. As she enters, she sees the human baby and blood covered paw prints that show the boy's parents were also Sabor's victims, and takes the boy away to save him from the predator. Her mate, Kerchak, the dominant male of the gorilla band, despises the human for his appearance, but Kala raises him anyway, naming him "Tarzan".
Tarzan grows up to become a strong gorilla-like man, whose best friends are a tom-boy female gorilla and a phobic elephant (Rosie O'Donnell and Wayne Knight). One day, Sabor attacks the gorillas and is defeated by Tarzan, which earns him some respect from Kerchak. But then a British expedition which wants to study gorillas appears, led by Professor Archimedes Q. Porter. His daughter Jane is attacked by baboons, surviving only after being rescued by Tarzan. Now Tarzan must decide where he belongs - and also prevent the trigger-happy hunter guide Clayton from ruining everything...
The film was very successful, outgrossing its predecessors Mulan and Hercules, and won an Academy Award for Best Song (Phil Collins' "You'll Be In My Heart"). It was the last big Disney hit until Lilo & Stitch 3 years later. The story was continued by an animated series, The Legend Of Tarzan, and two direct-to-video sequels, Tarzan & Jane (a compilation of some The Legend Of Tarzan episodes) and Tarzan II, an Interquel.
Awesome movie, great animation. Plus it has Tree Surfing. What more could you want?
