It really does remind me of an old sci-fi pulp comic book cover or novel - you can easily transpose it, with a little less spaceship, onto something like a pulp adaptation of At The Mountains of Madness. Intrepid explorers on vicious, alien terrain looking onwards towards unimaginable disaster. I just dig the retro action snap, the kineticism and willingness to show action and terror. In that sense, though it's a very modern poster in execution, it stirs up a feel of a bygone age - something of vitality and discovery long gone by Alien.
I dig the Sorcerer comparison, Salt! Though I do feel reasonably positive we'll have a better BO take.
