The finale was followed by a short preview that contained a montage of scene clips from the first four seasons. The announcer said:
"On the first day, he saved the President. On the second day, a city. On the third day, a nation. And on the fourth day, the world. But if you think you know what's coming next, you don't know Jack. 24 A new day begins next January, on Fox."
This was the first such preview to air after a season finale.
