Well, now that I got my Greek Myth story out of my system how about a story by committee?
I have the villains (Nazi SS in hiding) and I have an idea for an opening action scene in Brazil (which is where some of the Nazis were hiding).
My idea is that it's 1955 and it's been 10 years since the Nazis lost WWII. They are seeking an artifact that will give them power so they can return to Germany and prove that they are of a supreme race.
I've been toying with the Norse myth since deckard24 brought it up and because it was the predominant Pagan religion in Germany. I thought that the Norse Gods would fit even if in some ways they are similar to Greek Gods. I also thought I could somehow use the Nazis search for the swastika as the macguffin. Nazi archaeologists
did travel the globe to try and connect their beliefs to an ancient master race through the swastika.
After doing some research, I read that there is a belief that the pre-Roman Germanic peoples may have used the swastika as a symbol for the "Hammer of Thor".

It all ties together!
I scoffed at the idea before (sorry deckard24), but after seeing the swastika link I like it. Having a secret society of Nazi SS soldiers attempting to return to Germany to reclaim their lands and connect their race to the mighty Norse Gods by obtaining the Mjolnir is interesting.

I figure the film could could take us from, South America where the Nazis are hiding and known to operate from, then to Coppenhagen, Denmark and in the finale to Sweden or Norway where the Norsemen were known to have last settled.
