Here’s some set pictures from 24 Season 8 episodes 23-24.
Jack’s back! 24 came back downtown for the finale episode filming. This time they set up shop on Main St between 6th and 7th streets in the Historic Core. At the time I didn’t know that what they were shooting was for the final 2 hour episode, and now it makes perfect sense why they were a little curious who the guy with the camera was. I believe this scene takes place toward the very end of the finale, where Jack has been corned into a utility closet by CTU.
