EDIT- OK I see that AEG produced a D20 version of the TV show- was there ever anything written around the movie? prior to D20?
I worked on those books during my stint on the Spycraft design team, and I know we did several things to help reconcile the differences between the movie and the TV Series. I had a lot of fun working on the Stargate line, and ran a couple of pretty successful campaigns. If you end up picking up the books, I think you'll find a lot of them reference the events from the movies and extrapolate from those events as well.
