Some of the first spoilers for the return of Fox's action drama 24 have been released, including who will be joining Jack Bauer (Kiefer Sutherland).

The limited-run series, titled 24: Live Another Day, will premiere in spring 2014 and run for 12 episodes as opposed to 24, the usual for the show. Fox sent out a press release Friday revealing two characters that will be returning for the limited run series.

Kim Raver - who played Jack's love interest Audrey Raines on the show - will be returning for 24: Live Another Day. Audrey was first introduced in season 4 and was last seen in season 6. Audrey's father James Heller (William Devane) will also be returning for the revived series.

Raver and Devane joins Sutherland as well as Mary Lynn Rajskub, who is returning to play fan favorite Chloe O'Brian.

Fox also announced that 24 would be filming in London as part of the show's international storyline.

"24 has always had such a global sensibility," Sutherland said in the statement. "But to be able to tell this intense 24-style story with the beauty of Europe's history and architecture as the backdrop is going to be fascinating. Hopefully, by the time you're finished watching an episode, you'll feel like you've been there . . . on the edge of your seat."

Executive producer Evan Katz revealed that Live Another Day would pick up four years after the events of 24's last season. Fellow executive producer Manny Coto said that Jack will be "hunted by and hunting bad guys" while in London.

The 12-episode event series is set to air in spring 2014 on Fox but a specific premiere date has not yet been scheduled.
