24: Legacy is an American television series created by Manny Coto and Evan Katz that aired on Fox network from February 5 to April 17, 2017. The series is a spin-off of 24 which was created by Joel Surnow and Robert Cochran and its premiere served as the lead-out program for Super Bowl LI before moving to its regular time slot of Monday at 8:00 p.m. The series' premiere was watched by 17.6 million people, the lowest post-Super Bowl program viewership since 2003's Alias but the most viewed episode in the franchise's history.Consisting of 12 episodes, the show follows the life of war hero and ex-United States Army Ranger Sergeant Eric Carter (Corey Hawkins) using real time method of narration. Miranda Otto plays Rebecca Ingram, the former National Director of the now revived Counter Terrorist Unit in Washington, D.C. Set three years after the events of 24: Live Another Day, it adheres to the real time concept of covering the events of a 24-hour period and begins and ends at 12:00 pm. However, like Live Another Day, there is a 12-hour time jump within the final episode.

In June 2017, Fox announced that the series was cancelled. At the time, Fox had plans to develop a new incarnation of the 24 franchise. Those plans were later cancelled.
