Alternate versions

In the UK, the show was broadcast on BBC 2. The BBC does not run commercials during programming. Because of this, the episodes do not run in "real time". To account for this, every episode cuts out the opening line, "Events occur in real time".

The version of '24' that was shown on BBC2 in the UK had roughly a minute of added footage missing from the U.S release. The small extensions take place in the last 5 episodes and contain such as Terri telling Nina that she is pregnant and Jack Bauer reloading his guns at the pier shootout.

The premieres of season 2 and 3 originally aired commercial-free and were about 52 minutes long. There are also 44 minute versions for syndication that have had several scenes edited out.

In the German TV Version, Nina doesn't speak German to the people she works for but Spanish. Yet she is still ordered to relocate to Munich.

UK version of episode 2.6 was edited to remove some dialogue about a terrorist recruitment center. Original dialogue is: "You ever hear of the Finsbury Park mosque? It's considered to be one of the main recruitment centers for Islamic terrorists in the west. Our main targets are European Muslims with Western education, passports and the potential to blend into Western society. And do you know, where that mosque is located? Your hometown, London. So tell me Reza, how is my racial profiling going now?" This was changed to: "Our main targets are European Muslims with Western education, passports and the potential to blend into Western society. So tell me Reza, how is my racial profiling going now?"

Some episodes with a "Not under 16" rating were cut to be broadcast at primetime on German TV.
