Are you ready for Jack?
The clock has already started ticking for the thrilling and unpredictable fifth season of 24, which will involve new cast members Sean Astin (Lynn McGill), ("The Lord of the Rings"), Jean Smart ("Garden State") and Connie Britton ("Friday Night Lights) along with newcomer Brady Corbet ("Thirteen"). 24's "Day 5" will start with a four-hour, two-night season premiere on Sunday, Jan. 8 and Monday, Jan. 9 (8:00-10:00 PM ET/PT) on FOX. The second hour on Monday, Jan. 9 (9:00-10:00 PM ET/PT) will be the series' 100th episode. The fifth hour of 24 will air in the show's regular time period on Monday, Jan. 16 (9:00-10:00 PM ET/PT), and the intense series will then unfold on a weekly basis without repeats or preemptions all the way until the heart-stopping season finale. Season five picks up 18 months later as national security is brutally breached and the thrilling clock begins to tick again. A presumably dead Jack Bauer is actually living a new life with DIANE (Connie Britton) and her son DEREK (Brady Corbet). Panicky PRESIDENT LOGAN (Gregory Itzin) is running the nation, while composed BILL BUCHANAN (James Morrison) commands CTU alongside key operatives CURTIS MANNING (Roger Cross), EDGAR STILES (Louis Lombardi) and CHLOE O'BRIAN (Mary Lynn Rajskub). Also featured in season five will be Emmy Award-winning actress Jean Smart as First Lady MARTHA LOGAN. In addition, TONY ALMEIDA (Carlos Bernard) and AUDREY RAINES (Kim Raver) return in the upcoming season.
