In the movie 300, after Leonidas and the 300 decide to march North towards Thermopylae. The valley & mountains in the background are REALLY from Sparta, Grecet. The producers made had sent crews to take enough photos and videos of the valleygt to accurately portrait the landscape. It was eerie to watch the movie (I grew up in Sparta) and see the mountains all around as they really are. BUT (big but here) they march SOUTH while they should be marching NORTH.
When I watched it at the cinema (in Athens) back in the day, apparently there was one more Spartan in the venue and we both stood up and shouted (using different words) something to the effect of: hey morons, you are going the wrong way, you should be marchin North!!
