In recent years, Fox has brought back several of its biggest properties, including a 24 spin-off and revivals of The X-Files and Prison Break. As of now, none of the three properties are on deck for Fox's 2018-2019 season, but the network isn't closing the door completely on any of them. In fact, new installments of Prison Break and 24 are actively in development right now!
The fifth season of Prison Break aired in 2017 and saw original stars Wentworth Miller and Dominic Purcell return. According to Fox Chairmen and CEOs Dana Walden and Gary Newman, a new season is currently in the early stages of development. "We're just focused on getting the next iteration right," Walden said on a call with reporters Monday morning. "I don't anticipate there would be any significant announcements for several months."
The Corey Hawkins-led spin-off 24: Legacy also aired in 2017 but was canceled after one season. Wanting to find other ways of capitalizing on the original Kiefer Sutherland hit, Fox is already working with former 24 showrunner Howard Gordon and the show's creators Joel Sunrow and Robert Cochran on developing a new idea that that Fox is reportedly "excited" about. But again, it's too early to announce anything more specific, Walden noted.
As for The X-Files, which wrapped up the second season of its divisive revival in March, Newman said that the network was "really pleased" with the series but that there are "no plans to do another season at the moment." Given that The X-Files Season 11 finale marked Gillian Anderson's final episode as Dana Scully, this is probably welcome news to fans who were worried about a future in which The X-Files continued without their favorite skeptic.
However, creator Chris Carter has waffled on the idea of continuing the series with Anderson and Newman did use the phrase "at the moment," so who knows whether the Powers That Be will change their mind down the line and bring the sci-fi drama back in one form or another. (But please don't, Fox. We're begging you.)
