Season 7 aired after being off the air for almost 18 months due to the Hollywood Writer's strike. Large amounts of the season had already been filmed ready for the intended airdate of January 2008, and indeed the delays led to the creation of 24: Redemption. Africa was the planned start-point for season 7, but instead it was decided to make a TV movie of Jack's African adventure, as a prequel to season 7.
The premiere of Season 7 sees the “Events occur in real time” title card used for the first time since the the beginning of Season 3.
This is the first season to spotlight two main cast members with the “and” credit; Janeane Garofalo and Carlos Bernard. When both are featured in the same episode, however, Garofalo's name appears first, receiving a “with” credit instead. This also marks the first time a "with" credit is used for the regular cast.
This season is the first in which an actor, Carlos Bernard, receives an “and” credit in the main cast having appeared before on the show. Dennis Haysbert, William Devane, Jean Smart and Regina King have all been spotlighted in this manner since their first appearances and throughout their entire stint as regulars.
The room used for Jack's Senate hearing was also used as a courtroom in Changeling (2008), directed by Clint Eastwood and starring Angelina Jolie.
Writer and producer Manny Coto personally brought former Star Trek: Enterprise show runner and writer Brannon Braga onto the show for this season.
The first 17 minutes of the first episode of Season 7 were included as a special feature on the 24: Redemption DVD, ahead of Season 7 airing.
In the third episode (10:00 am - 11:00 am) Tony says “Charles Logan is a product of his environment” suggesting that the former President did not die from his stab wound in Day 6.
