cast as the neurotic elephant Tantor. However, Katzenberg persuaded Allen to leave the project for DreamWorks' Antz (1998) and in exchange, the studio would distribute his next four films. Agreeing to the deal, Allen departed from Tarzan in 1996 and was replaced by Wayne Knight. Animation The animators were split into two teams, one in Paris and one in Burbank. The 6000-mile distance and difference in time zones posed challenges for collaboration, especially for scenes with Tarzan and Jane. Glen Keane was the supervising animator for Tarzan at the Paris studio, while Ken Duncan was the supervising animator for Jane at the studio in Burbank. To make coordinating scenes with multiple characters easier, the animators used a system called a "scene machine" that could send rough drawings between the two animation studios. Meanwhile, following production on Mulan (1998), two hundred animators at the Feature Animation Florida satellite studio provided character animation and special effects animation where the filmmakers had to discuss their work through daily video conferences among the three studios. Keane was inspired to make Tarzan "surf" through the trees because of his son's interest in extreme sports, and he began working on a test scene. The directors expressed concern that Tarzan would be made into a "surfer dude", but when Keane revealed the test animation to them they liked it enough to use it in the film during the "Son of Man" sequence, with movements inspired by skateboarder Tony Hawk. Although Keane initially thought that Tarzan would be easy to animate because he only wears a loincloth, he realized that he would need a fully working human musculature while still being able to move like an animal. To figure out Tarzan's movements, the Paris animation team studied different animals in order to transpose their movements onto him. They also consulted with a professor of anatomy. This resulted in Tarzan being the first Disney character to accurately display working muscles. To prepare for animating the gorillas, the animation team attended lectures on primates, made trips to zoos, and studied nature documentaries, with a group of animators also witnessing a gorilla dissection to learn about their musculature. In 1996, the animation team went on a two-week safari in Kenya to take reference photographs and observe the animals. On the trip, they visited Bwindi Impenetrable National Park in Uganda to view mountain gorillas in the wild, and get inspiration for the
