FOX has made the decision to cancel "24" after eight successful seasons.
"Just found out we got the word officially," Mary Lynn Rajskub tweeted. "This is 24's last season."
Executive producer Howard Gordon told Variety that everyone determined the story had come to an end. "Kiefer and me and the writers had (a decision to make). What's the creative? What do we do? Is there any more story left to be told in this 24-hour format? We turned over every stone, and really determined that the story has come to an end in this 24-hour format."
Kiefer Sutherland said in a statement, "This has been the role of a lifetime, and I will never be able to fully express my appreciation to everyone who made it possible. While the end of the series is bittersweet, we always wanted 24 to finish on a high note, so the decision to make the eighth season our last was one we all agreed upon."
The final two-hour episode of "24" will air on May 24.
