Just heard an interview with Kiefer Sutherland on a local radio station. He confirmed that there would be a second season - it is being written now. He also said Dennis Hopper and Lou Diamond Phillips would be appearing on the show. As far as the end of this season, he said even he didn't know how the show would end. Even Jack could be killed off, for all he knew. He said they are currently working 5pm to 5am, so I assume their filming the last few night-time hours of the show.
