if you look at it, it wasnt finished and it reminded me of NATIVE NORTH AMERICANS (cuz i realize mesoamerican pyramids dont look like those on the trailer, and sorry if i didnt make myself clear) also the climates can all be in north america.
if thats not it i dont know what is, becuase the pyramids in the trailer dont look like eygptian pyramids they have edges and stuff sticking out, gonna go see it again just in case im wrong.I checked it out again and paused it around 0:36 or something not sure and i couldnt tell if it is (though the river in it seems like that of the nile but its to short even if its harvest and planting season)
also you never know if a group of people just captured them and brought the mammoths back to egypt, cuz you saw a army (the people that could capture them) and tundra (where the mammoths live).
but for the setting of the pyramid I will have to wait and see, cuz if they where gonna make a movie like this they would have a explaination but ovarall i wouldnt mind spending money to watch this.Also they say they will prolly have the people in it speak english becuase WB and the people that made 300 are making this movie so becuase spartans talked english people are guessing they will make mammoth hunters talk english too.
