After rumors that the whole idea may have been dropped, FOX has confirmed that the 2-hour 24 prequel is happening before Season 7 starts up in January. However, it will be airing Sunday, November 23 at 8ET, rather than in the fall as originally suggested. As I reported before, it will be bridging the gap between Season 6 and the new Season 7 which is trying to change up the formula a bit. Minor spoilers follow (mouseover them to view):

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," commented executive producer Howard Gordon. "Shooting in South Africa affirms everyone's commitment to making this season especially memorable for our fans."

The new season will be back on Mondays at 9ET starting January 2009.
