Have you watched this? It blew my mind. It gets about 60,000 views daily on Google Video. It basically is about how the world really works, and everything.
Yesterday my friend told me that the Smashing Pumpkins named their new album "Zeitgeist" so that when it was "googled" this movie would come up.
It's a great film but I haven't fully studied the Christianity part of it to say whether it's completely accurate or not. I have people telling me he's leaving something out, or he didn't get it completely right, etc.
