Keifer Sutherland heads the cast of the Fox series. The seventh season of the action drama is slated to debut in January 2008. Jones is a Tony Award winner for the drama Doubt, which she also toured in.

The TV series follows one (rather eventful) day (the title referring to 24 hours) in the life of Counter Terrorist Unit (CTU) agent Jack Bauer (Sutherland). Each of the 24 continuous weekly episodes in a season shows what unfolds in one, real-time hour. A ticking clock occasionally appears, fueling the show's signature intensity.

Feore has appeared on Broadway as Cassius opposite Denzel Washington's Julius Caesar and Off-Broadway as Claudius to Liev Schreiber's Hamlet. A veteran of Canada's Stratford Festival (Oliver!, Don Juan, Coriolanus), he has appeared on television in "Slings and Arrows," which is set at a Stratford-like fictional Canadian theatre festival. His numerous films include "Chicago," "Pearl Harbor," "City of Angels," and "The Chronicles of Riddick" among others. Feore recently appeared in HBO's "Bury My Heart at Wounded Knee."

Jones and Feore join a list of previous "24" guest stars who also have stage credits, including Jayne Atkinson (Enchanted April), Stephen Spinella (Angels in America), Jean Smart (The Man Who Came to Dinner), Peter MacNicol (Crimes of the Heart), Zeljko Ivanek (The Pillowman), Gregory Itzin (The Kentucky Cycle), Tamara Tunie (Julius Caesar), Logan Marshall Green (King Lear), Harry J. Lennix (Radio Golf), Lou Diamond Phillips (The King and I) and James Cromwell (Hamlet), among others.
