pirates curse production

Production
Shooting began on October 9, 2002 and wrapped by March 2003.[6] The quick shoot was only marred by two accidents: as Jack Sparrow steals the Interceptor, three of the ropes attaching it to the Dauntless did not break at first, and when they did snap debris hit Depp's knee, though he was not injured, and the way the incident played out on film made it look like Sparrow merely ducks. A more humorous accident was when the boat Sparrow was supposed to arrive in at Port Royal sank.[1] In October the crew was shooting scenes at Rancho Palos Verdes, by December they were shooting at St. Vincent and in January they were at the cavern set at Los Angeles.[16] The script often changed with Elliott and Rossio on set, with additions such as Gibbs (Kevin McNally) telling Will how Sparrow escaped from an island, strapping two turtles together with rope made of his back hair, and Pryce was written into the climactic battle to keep some empathy for the audience.[1]
Because of the quick schedule of the shoot, Industrial Light & Magic immediately began visual effects work. While the skeletal forms of the pirates revealed by moonlight take up relatively little screentime, the crew knew their computer-generated forms had to convince in terms of replicating performances and characteristics of the actors, or else the transition would not work. Each scene featuring them was shot twice: a reference plate with the actors, and then without them to add in the skeletons,[7] an aesthetic complicated by Verbinski's decision to shoot the battles with handheld cameras.[1] The actors also had to perform their scenes again on the motion capture stage.[11] With the shoot only wrapping up four months before release, Verbinski spent eighteen-hour days on the edit,[1] while at the same time spending time on six hundred effects shots, two hundred and fifty of which were merely removing modern sailboats from shots.[17] He also had to quickly manage the score with Klaus Badelt and Hans Zimmer, who headed 15 composers to finish the score quickly.
