landscape. For the chocolate river, McDowell insisted on having the river look edible, saying "in the first film, it's so distasteful." According to Tim Burton, "the important thing for me was that we wanted to give the chocolate river a really chocolatey feel, give it a weight, not just brown water. That's why we tried to use a real chocolate substitute, to give it a movement and texture." Joss Williams oversaw the creation of a faux chocolate concoction, taking months to create a non-toxic edible substance with the right consistency. The final mixture, developed by a UK-based chemical company called Vickers, was a mix of water and a thickening agent known as Natrosol, with food dye used to achieve the brown coloring. The river was 270 feet long, six feet deep, and consisted of 192,000 gallons of faux chocolate while 30,000 gallons of the same material made up the waterfall. Wonka's boat, used by the characters to travel down the chocolate river, took 20 weeks to build and incorporated 54 animatronic Oompa-Loompas, along with its own internal rowing mechanism. Colleen Atwood, who served as the costume designer on every live-action Tim Burton film from 1994's Ed Wood to 2019's Dumbo, was set to reprise her position on Charlie and the Chocolate Factory but ultimately declined citing "personal reasons". Burton then selected Italian costume designer Gabriella Pescucci. Ten different jackets and overcoats were designed to find the right look for Willy Wonka. Pescucci described the film's wardrobe as "contemporary, but with old world styling". Wonka's latex gloves, which Burton added as a symbol of his detachment from society, were provided by a London-based latex fetish BDSM clothing company. Filming Principal photography for Charlie and the Chocolate Factory started on June 21, 2004. While the main set pieces were filmed on soundstages at Pinewood Studios in England, the crew also shot on several locations across the country, with the toothpaste factory filmed at a CompAir factory in High Wycombe, and Veruca Salt's manor filmed at Hatfield House for the interior shots and Wrotham Park for the exterior. Various establishing shots were filmed in Germany, Yemen, and the United States. Tim Burton shot Charlie and the Chocolate Factory simultaneously alongside Corpse Bride. Composer Danny Elfman, screenwriter John August, and production designer Alex McDowell served in the same position for both movies. Johnny Depp, Helena Bonham Carter, Deep Roy, and Christopher Lee provided their
