(development) Originally with the performance artist who entertains the affluent patrons, Östlund was considering modelling the character after G.G. Allin, but deciding that that would be too “extreme”, he fell back on his interest in animal imitations. In crafting the scene, his concept was: “this internationally recognized artist is pretending to be a wild beast. What happens when he enters a room full of people in tuxedos?” The scene was inspired by a real incident with the artist Oleg Kulik, who performs as a dog and had attacked people at a notorious event in Stockholm. Other artists parodied in the film include Julian Schnabel, Robert Smithson and Carl Hammoud.
Making Africa seem authentic was especially important to the filmmakers, since the film was shot in England, except for six weeks in Gabon, filming background by helicopter without the cast. A working waterfall and a 100-foot-long collapsible pier were assembled at Warner Bros.’ Leavesden studios. Seven versions of the African jungle were constructed to show different scenery throughout the filming. Plants from Holland were mixed with trees sculpted by the art department. Kedleston Hall stood in for the Greystoke Manor, and a cedar tree on the grounds of Highclere Castle served as the setting for an early pivotal scene between Tarzan and Jane. (wiki)
