If by some miracle Jericho does indeed come back, it will be without one cast member.

Sprague Grayden, who played Heather on the CBS show, has joined the cast of FOX's 24 prequel. She'll play the First Daughter, the daughter of the President of the United States.

This news comes on the heels of more casting news announced last week. It's an interesting cast: Grayden joins Cherry Jones, Janeane Garofalo, Robert Carlyle, Tony Todd, Gil Bellows, and Eric Lively (oh, and Kiefer Sutherland). The new season of 24 starts in January, but this prequel will air this fall.

Of course, maybe she could come back to Jericho too When she was on that CBS show, she had a role on Weeds as well. And while she's on 24 she's also going to be on FX's Sons of Anarchy. Now that's job security. She also had regular gigs on John Doe, Joan of Arcadia, Over There, and Six Feet Under.
