Stargate Universe

A band of soldiers, scientists and civilians are forced through a stargate when their hidden base comes under attack. The desperate survivors emerge aboard an ancient ship, The Destiny, which is locked on an unknown course and unable to return to Earth. Faced with meeting the most basic needs of food, water and air, the group must unlock the secrets of the ship’s stargate to survive. The danger, adventure and hope they find on board Destiny will reveal the heroes and villains among them.

hrm… Start Trek Voyager, anyone? What the hell…
There’s a short video with some of the cast and some footage here.

I think by “Grittier” they mean, BSG Style… It felt like I was watching a BSG promo.
Ah well, Battlestar-Gate is better than no Stargate!
