Re: Is the Stargate movie required viewing before seeing SG-1?
Casting lookalike actors for Carter and Teal'c is kind of backwards casting, but even so Meg Ryan would be a good choice but Sandra Bullock was an up and coming actress at the time too. And both Brain Thompson and Michael Dorn would be good choices to play Teal'c given the small role he might have in the film.
