I just recently watched that movie, and I got REALLY into it. But as the good student I am, I made sure I didn't just watch that movie and not check the facts.
Unfortunatly almost all the sources in that movie came from about 8 places. Out of those 8 places, most of them which are books, you will quickly see that the sources are completely unreliable.

I hate to inform those who watched this movie and enjoyed it because of the "facts" but there is almost no connection between Horus and Jesus, and I wont get into the 9/11 thing and the federal reserve except to say, just check the reliability of those sources.
That's all.
