Judy Davis has signed on for a recurring role in the Fox limited series 24: Live Another Day. She will play a vicious German arms dealer named Margo. It isn't known exactly how many episodes she will appear in.

The actress is the first cast member to join the 12-episode series that didn't appear on 24. Kiefer Sutherland (Jack Bauer), Mary Lynn Rajskub (Chloe O'Brian), Kim Raver (Audrey Raines) and William Devane (James Heller) have been confirmed to reprise their roles.

The show will be shot in London, with the story set four years after the 24 series finale. While the show will retain the original 24's one day format, the 24-hour period will be condensed into 12 episodes, with some hours in that day being skipped.

Howard Gordon, Evan Katz, Manny Coto, David Fury, Robert Cochran, Brian Grazer, Jon Cassar and Kiefer Sutherland are serving as executive producers, with the series slated to debut in the spring of 2014 on Fox. It isn't known when production will get under way.
