Here are a few of the latest tidbits on your favorite cancelled shows, as well as their reunions and revivals.

The 4400 and The Dead Zone — EOnline asked USA about the possibility of a mini-series or movie to wrap up either of the freshly cancelled series. According to an unnamed source, there’s no chance you’ll see any kind of conclusion on that channel. Still, there is a small possibility that another channel could step in or something could be produced for a direct-to-DVD release. We’ll keep you posted on any new developments.

The Next Great American Band — If you’re one of the few who have been watching Band on FOX, don’t forget to watch the season finale Friday night. The competition show’s been such a big ratings disappointment that this will likely be the series finale as well.

G.I. Joe — Three more roles have been cast in the upcoming live-action G.I. Joe movie. The Cobra Commander’s ninja bodyguard, Storm Shadow, will be played by Korean star Byeong-Heon Lee. On the good-guy side, Shana “Scarlett” O’Hara will be played by Rachel Nichols (Alias) and Adewale Akinnuoye-Agbaje (Lost) will portray ordnance specialist Heavy Duty. The movie’s expected in theaters on August 9, 2008.

Knight Rider — Justin Bruening was injured last week while filming the new NBC movie. Bruening apparently hurt his knee so badly in a fight scene that he needed to be taken to a local hospital. He was treated and released and will likely return to filming soon.

Dallas — The NY Post is reporting that John Travolta (Welcome Back, Kotter) is no longer part of the upcoming Dallas big-screen remake. The project’s been in the works for a few years and several attached directors and actors have come and gone but Travolta had remained set to play bad guy J.R. Ewing. The newspaper reports that Ben Stiller has been signed for the role but the actor’s reps deny it.

Sex and the City — Looking forward to the reunion movie? If so, you may be happy to know sequels may be in the works. The UK’s Daily Mail is reporting that the producers are so confident that the movie will be a success that a second movie script is being developed. An unnamed source contends that the sequel option in the four actresses’ contracts will be exercised to possibly make not one, but possibly two more movies. Look for Carrie, Samantha, Miranda and Charlotte on the big screen this Spring. Stay tuned!
