I have been googling around about Stargate SG1 and I found an article dated 03 August 2008 featuring a commentary on several interviews with Christopher Judge. In this article it is mentioned that 3rd movie may be in the works and if approved should have begun filming in January '09. I know that was 7 months ago that filming should hve begun. I have been unable to find any other info about this. I have searched through the forums here and i find no mention of it unless I missed them. Does anyone have any knowledge or news on this?
One of the interviews is at the French AlloCiné Blogs website and is from Judges appearance at the Reunion Stellaire convention held June 27-29. The second is a video interview posted at Stargate: Continuums page at play.com and took place in London, possibly at the time of the Chevron 7 convention held June 13-15.
I don't know if I am allowed to post links here so I will refrain until I am certain I will not be breaking any rules.
