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. In directing Skyfall and Spectre, Mendes became the first director to oversee two consecutive Bond films since John Glen directed The Living Daylights and Licence to Kill in 1987 and 1989. Skyfall writer John Logan resumed his role of scriptwriter, collaborating with Neal Purvis and Robert Wade, who returned for their sixth Bond film.[N 4] The writer Jez Butterworth also worked on the script, alongside Mendes and Craig. 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.
