Howard Gordon, Executive Producer and Showrunner of "24," has set his next project, but before we talk about that, here’s what Gordon told The Hollywood Reporter about the possibility of ’24" continuing next season, even on another network:
" ‘Discussions are still being held; the book hasn’t been closed,’ he said. ‘If there is ’24’ past Season 8,’ he added, ‘I will be part of that,’ though probably not as showrunner. He also said that star Kiefer Sutherland, who has no deal for the show beyond the current season, ‘is inclined to do another season if there is a good story.’ "
Gordon, who has a deal with Twentieth, told THR that "his next project is to co-write an American version of ‘Prisoners of War.’ The Israeli original followed three soldiers who return home after 17 years as captives of the Syrians; the new version, tentatively called ‘Patriots,’ follows three U.S. soldiers who were presumed killed during the Iraq war but are found in a cave after ten years."
Furthermore, THR says that Gordon would co-write the new project "with ’24’ executive producer and writer Alex Gansa and Gideon Raff; the latter created the original series for Keshet Broadcasting."
