There are plans for both an SG-1 and Atlantis film, but it's been said that the cancellation of Universe nullified the Atlantis film. In all probability, that will be the case for the SG-1 film as well. Speaking of which, there are plenty of threads for discussing the potential Atlantis film, so let's stick with discussing the potential third SG-1 film. As I understand it; there is a script, O'Neill would be the central character, and everyone from the main cast would be involved except for Vala. I hope that includes Mitchell and Landry. As for Vala, she was so central to the final two seasons and both movies, to leave her out just isn't right unless Claudia Black is the one who backed out. At the very least, give Vala a cameo, perhaps a brief scene early on that tells us why she won't be joining SG-1 for whatever adventure the movie is about. That's all moot if there's no movie to be filmed, though. My main concern is that the actors are getting older, and the TV audience may not care by the time this movie happens. SG-1 is a popular show, but it doesn't have mass appeal the way Star Trek or The X Files has.
