As a fan of the Stargate TV universe, which the proposed new Stargate movies were definitely going to remove from canon, I’m OK with this. Especially seeing how the same team did with Independence Day: Resurgence.
Dean Devlin told Empire Online that the plans to make another Stargate movie, and reboot a potential new series, are stalled, possibly indefinitely:
It looked good for a couple of months, but now it's not looking so good. There are just a lot of things that have to fire at the same time, and there was a moment where I thought it was all firing at the same time, and then it all kind of fell apart.
Devlin added that he thinks the problem is with big studio thinking, which wants a franchise in theatres no matter what and doesn't really care about the quality. We've heard that before.
Devlin added, "Listen, I think if we did Stargate right, the fans would like it and we could do something really good. But if we screw it up, they will reject it. As they should. But I kind of don't want to do it if I think that we'll screw it up, and that's one of the things that's holding us back." Well, at least he's willing to fight for it.
Dean Devlin's been the executive producer behind a couple of TV shows, Leverage and The Librarians, that I love a lot. But as I mentioned, I'm also a fan of the Stargate TV universe, which was made without Devlin and Roland Emmerich's involvement. Devlin's on record as saying that the new movies would ignore all that had been established there, and, while it wouldn't eliminate the shows from existence, that is a shame. That's a whole universe that took years to build that they were just going to ignore.
So, instead of being sad that there aren't going to be more Stargate movies from Devlin and Emmerich, I'm just going to bust out my SG-1 box sets.
