Producer Michael G. Wilson developed the film's plot while the previous film in the series was being shot, and Purvis, Wade, and Haggis contributed to the script. Although Craig and Forster wrote some sections themselves during the screenwriter strike, they received no writing credits in the final cut. The title was chosen from a 1959 short story in Ian Fleming's "For Your Eyes Only", though the film does not contain any elements of that story. Location filming took place in Mexico, Panama, Chile, Italy, Austria and Wales, while interior sets were built and filmed at Pinewood Studios. Forster aimed to make a modern film that also featured classic cinema motifs: a vintage Douglas DC-3 was used for a flight sequence, and Dennis Gassner's set designs are reminiscent of Ken Adam's work on several early "Bond" films. Taking a course away from the usual Bond villains, Forster rejected any grotesque appearance for the character Dominic Greene to emphasise the hidden and secret nature of the film's contemporary villains. The film was also marked by its frequent depictions of violence, with a 2012 study by the University of Otago in New Zealand finding it to be the most violent film in the franchise. Whereas "Dr. No" featured 109 "trivial or severely violent" acts, "Quantum of Solace" had a count of 250—the most depictions of violence in any "Bond" film—even more prominent since it was also the shortest film in the franchise.
