According to Digital Spy, we might see 24 on the big screen:
The plans would involve shooting a movie version of 24 this summer, after the current fifth season wraps and before the sixth season airs in 2007…. "It’s certainly something that I’ve expressed an incredible amount of interest in doing," [Kiefer Sutherland] said. "It is something that Joel, Howard and Bob and I have all talked about. One of the real difficulties, and Joel’s expressed it in a number of interviews, is that any time they got really close to having a great idea for a film, we needed it for episode 18, so there it went."
The show is great, but I donâ€™t know if a 24-hour movie will fly with the public.
