In theory, I really like this poster. It conveys well how small and seemingly defenseless man is when matched with the enormous and powerful mammoth, having only primitive weapons to defend himself. And I think that goes to the main appeal of the movie: showing the primitive man as he tackles a world that is much more daunting and full of dangers than our current world.
But that is in theory. In practice, this poster, and the first trailer for that matter, feels a little underwhelming. Unfortunately I can’t quite put my finger on what is wrong with it. Perhaps the image seems too fake? I’m not sure, but the poster just isn’t giving me the wow feeling I thought it would.
