In this film, the gun barrel sequence was moved to the end, which Wilson explained was done for a surprise, and to signify that the conclusion of the story had begun in the previous film. The opening credits were created by MK12. Having worked on Forster's Stranger than Fiction and The Kite Runner, MK12 spontaneously began developing the sequence early on, and had a good idea of its appearance which meant it did not have to be redone when the title singer was changed. MK12 selected various twilight colours to represent Bond's mood and focused on a dot motif based on the gun barrel shot. MK12 also worked on scenes with graphical user interfaces, including the electronic table MI6 uses, and the Port-au-Prince, Haiti title cards. Effects Quantum of Solace was the last in Ford Motor's three-film deal that began with 2002's Die Another Day. Although Ford sold over 90% of the Aston Martin company in 2007, the Aston Martin DBS V12 returned for the film's car chase around Lake Garda; Dan Bradley was hired as second unit director because of his work on the second and third Bourne films, so the film would continue the gritty action style begun in Casino Royale. He had intended to use Ford GTs for the opening chase, but it was replaced by the Alfa Romeo 159. After location filming in Italy, further close-ups of Craig, the cars and the truck were shot at Pinewood against a blue screen. Originally, three Alfa Romeos were in the sequence, but Forster felt the scene was too long and re-edited it so there would be two Alfas were chasing Bond. Ten cars were supplied by Aston Martin. Six 'hero' cars, needed for close-ups and promotional work, all survived filming unharmed with four more cars used for special effects and stunts. Fourteen cameras were used to film the Palio di Siena footage, which was later edited into the main sequence. Aerial shots using helicopters were banned, and the crew were also forbidden from showing any violence "involving either people or animals." To shoot the foot chase in Siena in April 2008 four camera cranes were built in the town, and a cable camera was also used. Framestore worked on the Siena chase, duplicating the 1,000 extras during principal photography to match shots of the 40,000-strong audience at the real Palio, removing wires that held Craig and the stuntmen
