Gateworld recently caught up with Stargate Atlantis co-creator Brad Wright and got a bit more info on the planned 3rd live action Stargate show, Stargate Universe.
“The idea of Stargate Universe is that it is set on a ship that was part of an Ancient experiment that was set in motion probably millions of years ago — one that they never saw to fruition, but that we can,” Wright told GateWorld exclusively. “They got busy with the whole ascension thing.”
The experiment is “to send a ship across the universe, and to send one ahead of it to seed the galaxies with Stargates, and that they would one day use the ninth chevron to get there [to the ship]. And that’s what Stargate Universe is.”
The story also goes on to explain why we might not see Stargate Universe until after Stargate: Atlantis finishes, although he is sounding like they’d like to do more Stargate movies which would be very cool.
