Last year (february 2011) I had the opportunity and the luck to met Christopher Judge (AKA TEAL'C from SG1) and as I knew he was develloping a Tv show concept based on war between Heaven and Hell, I have made several research for him and I gave him in proper hand.
More like some researches for his development plot.
One year and four month later, I dunno if the project is still on track but I assume I can show you what I have done.
It's not official at all.
I did all the research in a short time ( a week and after my day work)
