In March 2013 Mendes said he would not return to direct the next film in the series, then known as Bond 24; he later recanted and announced that he would return, as he found the script and the plans for the long-term future of the franchise appealing. Nicolas Winding Refn would later reveal that he turned down an offer to direct the movie. In directing Skyfall and Spectre, Mendes became the first director to oversee two successive Bond films since John Glen directed five consecutive films, ending with The Living Daylights and Licence to Kill in 1987 and 1989. Dennis Gassner returned as the film's production designer, while cinematographer Hoyte van Hoytema took over from Roger Deakins. In July 2015 Mendes noted that the combined crew of Spectre numbered over one thousand, making it a larger production than Skyfall. Craig is listed as co-producer. He considered the credit a high point of his career, saying, "I'm just so proud of the fact that my name comes up somewhere else on the titles."The film's usage of the Spectre organisation and its characters marked the end of long-standing litigation between Eon Productions and producer Kevin McClory, who sued James Bond creator Ian Fleming in 1961 claiming ownership over elements of the novel Thunderball, and in an out of court settlement two years later, was awarded the novel's film rights, including Spectre and its characters. McClory died in 2006, and in November 2013 MGM and the McClory estate formally settled the issue with Danjaq, LLC—sister company of Eon Productions—with MGM acquiring the full copyright film rights to the concept of Spectre and all of the characters associated with it. It has been suggested that with the acquisition of the film rights and the organisation's re-introduction to the series' continuity, the SPECTRE acronym was discarded and the organisation reimagined as "Spectre".When Sony Pictures Entertainment renegotiated with Metro-Goldwyn-Mayer the deal to co-finance the Bond franchise in 2011, they were tasked to provide 25 percent of the negative cost of both Skyfall and Spectre,  in exchange for receiving 25 percent of the profits plus distribution fees for overseeing its worldwide rollout. When the film was announced in June 2013, the budget was not yet fixed, but was certain to be higher than the $210 million of Skyfall due to foreign locations and bigger payments for Mendes and Craig. In November 2014, Sony was targeted by hackers who released details of confidential e-mails between Sony executives regarding several high-profile film projects. Included within these were several memos relating to the production of Spectre, claiming that the film was over budget, detailing early drafts of the script written by John Logan, and expressing Sony's frustration with the project. Eon Productions later issued a statement confirming the leak of what they called "an early version of the screenplay". Eon resisted Sony and MGM's arguments to cut down on stunts and location work to reduce the budget, but managed to secure tax incentives and rebates, such as $14 million from Mexico. Spectre has a final budget estimated between $250 million and $275 million.
