Grayden has signed on to play the President’s daughter on the upcoming seventh season of the hit TV show featuring Jack Bauer. The recurring role has Grayden playing daughter to season 7 President Cherry Jones.

Fox recently announced their fall schedule along with all the other networks. “24” won’t be returning until January when Season 7 will air with uninterrupted episodes. However, as we already know, a two hour prequel movie will be airing this fall that will bridge the gap between Season 6 and Season 7. Fox announced that the prequel will air on November 23, 2008.

In related news, sources confirm that Scottish actor Robert Carlyle (The Full Monty) has been cast in the prequel movie as Benton, Jack’s mentor in South Africa where a lot of the film takes place. Carlyle’s role is not expected to spill over into the show’s seventh season, but with “24″ you never really know.

Fox also gave us some press on the prequel as well as Season 7:

Shot on location in South Africa, Jack Bauer battles an international crisis, while here at home the nation prepares for a new president on inauguration day. Taking place just a few months before the new day dawns, the prequel will set the stage and raise the stakes for Season Seven.

“We’re excited about the prequel because it explores Jack’s complex emotional state of mind and still has all the signature excitement and suspense that fans have come to expect from 24,â€? commented executive producer Howard Gordon. “Shooting in South Africa affirms everyone’s commitment to making this season especially memorable for our fans.â€?

Celebrating its 150th episode this season, the series has resumed production on “Day 7� and will unfold without interruption in its regular time period Mondays (9:00-10:00 PM ET/PT) beginning in January 2009.

Set in Washington, DC, “Day 7� finds CTU dismantled and Jack Bauer on trial. Bauer’s day takes an unexpected turn when former colleague TONY ALMEIDA (Carlos Bernard) returns. Meanwhile, President ALLISON TAYLOR (Cherry Jones) leads the country alongside White House Chief of Staff ETHAN KANIN (Bob Gunton) and First Gentleman HENRY TAYLOR (Colm Feore).

A national security crisis prompts an investigation by a team of FBI agents including Agent JANIS GOLD (Janeane Garofalo), Agent RENEE WALKER (Annie Wersching), Agent LARRY MOSS (Jeffrey Nordling), Agent SEAN HILLINGER (Rhys Coiro) and security specialist MICHAEL LATHAM (John Billingsley). Although CTU is no longer, CHLOE O’BRIAN (Mary Lynn Rajskub) and BILL BUCHANAN (James Morrison) are back for another momentous day of shocking events.

However, there will be a two hour prequel film this fall that bridges season 6 with season 7. I’m guessing the film will probably be helpful because it sounds like a lot has changed. Apparently we’re going to find CTU disbanded after the events of season 6 and Jack Bauer on trial for his actions (the guy can’t catch a break). However, a major national security incident occurs when the firewall responsible for protecting America’s government computer infrastructure is breached. I’m guessing they’re going to need Jack to get “involved” again.

A lot of people weren’t that happy with last season so it remains to be seen if the long hiatus will be good for the ratings or bad. I’m a huge fan of the show, but I too felt last season was lacking in a lot of ways (the music stunk for sure). I’m hoping the extra time was used wisely be the show’s producers to get back to all the things we loved about it from the very beginning while still allowing the characters and situations to grow intelligently. (I’m not sure how many more times Jack is going to have to prove himself to be a patriot before I’m going to scream.) Let’s hope they get it right.

The producers of Fox’s “24” are developing a two-hour “prequel” to the upcoming seventh season of the television thriller. The movie is going to be designed to bridge the two-year gap between Seasons 6 and 7 and is targeted to air in the fall, leading to the show’s January return.

As pretty much everyone knows, the writers strike stopped work on the seventh season of “24″ with just eight episodes filmed. Fox decided against airing any episodes until the season could be completed which meant putting off the season completely until January, 2009. At one point a few weeks ago there were rumors that Fox would split the season in two and air half in the fall and half in the new year, but Fox was quick to put that rumor to bed.

The upcoming seventh season of the Emmy-winning series is set in Washington and features the first female U.S. president, played by Cherry Jones. The “24″ writing team is back at work, with production on the remaining episodes of the seventh season slated to begin in April. However, the series will have to continue without series co-creator/executive producer Joel Surnow because he left the show at the end of the strike for reasons unclear.

I am uncertain what Surnow’s departure will mean for the show. I also have not heard much about the announced big-screen adaptation of the show that was originally supposed to hit theaters next year.
