war. While Leone developed Vincenzoni's idea into a script, the screenwriter recommended the comedy-writing team of Agenore Incrucci and Furio Scarpelli to work on it with Leone and Sergio Donati. According to Leone, "I couldn't use a single thing they'd written. It was the grossest deception of my life." Donati agreed, saying, "There was next to nothing of them in the final script. They only wrote the first part. Just one line." Vincenzoni claims that he wrote the screenplay in eleven days, but he soon left the project after his relationship with Leone soured.

Film director Alex Cox suggests that the cemetery-buried gold hunted by the protagonists may have been inspired by rumors surrounding the anti-Communist Gladio terrorists, who hid many of their 138 weapons caches in cemeteries.

When Lee Van Cleef was again cast for another Dollars film, he joked, "the only reason they brought me back was that they forgot to kill me off in For a Few Dollars More". The film's working title was I due magnifici straccioni (The Two Magnificent Tramps). It was changed just before shooting began when Vincenzoni thought up Il buono, il brutto, il cattivo (The Good, the Ugly, the Bad), which Leone loved. In the United States, United Artists considered using the original Italian translation, River of Dollars, or The Man With No Name, but decided on The Good, the Bad and the Ugly. Filming Production began at the Cinecittà studio in Rome again in mid-May 1966, including the opening scene between Eastwood and Wallach when Blondie captures Tuco for the first time and sends him to jail. The production then moved on to Spain's plateau region near Burgos in the north, which doubled for the Southwestern United States, and again shot the western scenes in Almería in the south of Spain.
