24

In the scene where Jack and Renee are interrogating Schecter about the location of Tony Almeida, there's a line omitted in Renee's speech according to the 24 preview (sneak peak) released in late 2007 to promote the beginning of season 7 in January 2008, which then was moved to January 2009. When Jack says "It's your call!", Renee answers "Do whatever it takes" and then she says "Torture him if you have to". This last line is the omitted one in the episode.

When Jack is holding a gun to Schecter's head, we can clearly see that there is no clip in it.

When Ethan Kanin (Bob Gunton) enters the briefing room to tell the President that Aldridge is holding off his story, he calls him "Henry Aldridge" instead of "Kevin Aldridge".

When John Rosenfeld, who plays Kevin Aldridge, reaches for his cup when talking to Henry Taylor (Colm Feore), he initially appears to have forgotten where he left it.
