I saw that movie in the theater and did the exact same thing afterwards. Although I later learned that the theory proposed in the movie was not original, it was a plot twist that I certainly did not see coming.
There is no shortage of writing on the Masons, Illuminati, Trilateral commission etc. Unfortunately, it is hard to tell if any of it is factual, or just the fantasy of writers looking to cash in on the whole conspiracy theory hysteria.
Masons themselves have websites too, and they do give out some interesting info. It would be appropriate for me to insert a few great links here, but I don't have any available.
