I never knew Djimon Hounsou was in the original Stargate. And I agree, he would have been a good choice to play Teal'c in our imaginary Stargate film.
I still stand behind having Meg Ryan play Carter. But I wouldn't mind seeing some other ideas, too.
I also forgot that French Steward played one of the Airmen under O'Neil's command. Been a while since I've seen the first fillm; I'll need to rectify that soon (of course, once I see the film again, it's hard to not rewatch the series....).
