Announcement of the movie was made online by TV Guide, October 11, 2006:
Stargate SG-1 may be winding down its 10-year-run this spring, but here’s some exciting news for its fans. MGM has granted a green light — and enough money — to produce two movies, most likely for DVD, executive producer Brad Wright tells TV Guide. The first flick will tie up most of the finale’s loose threads — “It’s the climax of the Ori story line” — and will be written-directed by exec producer Robert Cooper. The second film, penned by Wright, will involve time travel, and both projects should debut in the fall of 2007. Though no deals are signed, SG-1’s stars are said to be “very eager” to continue.

“They’re not big-budget [films] by any definition, but for us it’s pretty good,” says Wright. “As we’ve proven over the years, just give us little more money and we can make pretty good television, or DVDs.
“There’s a sense of an era for us ending,” Wright continues, “but at the same time, we’re all positive because of the prospect of continuing forward with movies and the introduction next year of Stargate Worlds, a massive multiplayer online game.”
