What about the obvious? America has some iconography built in that is perfectly suitable. Uncle Sam is a perfect avatar of America. And I'm sure if you wanted a darker aspect you could get the Uncle Sam that buggers hs nephew when mom's away too, if you really wanted. Then there's the Bald Eagle, patron animal spirit of the USA. There's all the totem work you need right there. You could also call Lady Liberty (even though she's French) if you wanted a god/goddess duality with Uncle Sam. Add in some guns, money, porn and hanburgers and you're on your way.
But really, what I think you want is less the spirit of America itsels so much as particular aspects of it. In which case, just do that specificly. If you want the demon of corrupt politics, dress in a business suit and tie, cover yourself in oil and blood, and kick some darkies around and I think you'll find what you're looking for.
At the very least, that'll make for some far mroe intersting filmmaking |
