Creature at start of trailer

That's my main reason for thinking that it's an Engineer in primordial Earth's past and probably not David: the water. We have to account for where all that water is situated in the movie. If it's an infected crew member, they somehow got off the planet and are on another planet toward the end of the movie. If it's an Engineer in Earth's past, he's there visiting our planet while the seas are forming and drops off some of the bioformer, which may be in his blood, into the water to allow it to start the process of evolution.

dtrisml "I think whoever is seen at the beginning of the trailer is likely also the same figure who we've previously seen activating the chair array (pale, bald, muscular human-looking male). At least it *feels* to me like the same being (and also note the resemblance to the "head"." My thoughts exactly.

Xenotron: Don't you think that will give too much of the story away? If we're told at the start of the movie, or it's directly implied by just what we see, won't that take away some of the mystery? I do like your idea better than the mutated human, but one of the "staff" told us it was a mutating human! They wouldn't lie, would they?! (Wish this forum had smilies!)

@ Shambhala: I like your theories. I think an interesting compromise would be to say that what's in the urns is possibly the *remains* of the "Gods" in a preserved form, and that their "resurrection" and will is carried out biologically, by their genetic essence infecting and changing unwitting explorers who happen upon the "tombs". This may also tie in with the enigmatic voice-over about the "king".

No it doesn't give too much of the story away and here's why: The trailer is outright telling you that aliens came to Earth in the past. This is where the story starts, not where it ends. It's setting up the premise for the movie; it's the impetus for our characters to start on their discovery. Plus, the Engineer creating life on Earth isn't like a major spoiler or anything and it's certainly not the whole story. You see, aliens creating life on Earth in the past isn't a story. Aliens creating life on Earth, humans figuring it out and finding the creators, and then the struggle between the humans and the creators is a story. Story requires struggle and the protagonist overcoming the antagonist.

Alien = Ash Aliens = Bishop Alien Resurrection = Call Prometheus = David So vickers wont be an android. ABCD....

What i'm interested in knowing is what the disc-shaped thing overlooking the waterfall is. It definitely looks like a fixed structure to me. Also, theoretically, there would have to be water *somewhere* on the planet in order for there to be clouds (which it seems to have an abundance of). The waterfall may not be in the "valley of the tombs", but it might be someplace nearby perhaps(?). At any rate, the rock in both locations is pretty clearly of the same sort of volcanic basalt-type makeup, and the cloudy, gloomy-skied ambience is also pretty much the same as well.

DJAB, LOL... plus Vickers is a gun anyway...

Here is how I think the movie progresses: 1. The story of man's creation by an alien according to Elizabeth Shaw. 2. The mission to a planet pointed to by the "invitation" star map. 3. The discovery of the ampules and the head. Skeptical moviegoers and the Prometheus crew are to believe Shaw's story was correct. 4. Things start to go wrong and people start getting infected. 5. The discovery of the old derelict underground and the reason for it's existence. 6. Shaw's pregnancy and her realization that she was completely wrong. 7. She has to convince everyone else to sacrifice themselves on her new "theory" 8. The engineer takes off from one of many hangers in a new looking ship. Those who can do something finally believe her and ram it in an act of self sacrifice. This ship is grounded but the Engineer lives so the problem was not solved.. 9. Shaw gives birth to a biological plague that arose from human interference in alien technology. 10. The Engineer takes it back to the older ship (the actual derelict) and while readying the ship is infected by a facehugger. He awakens and continues to ready the ship. The chestburster emerges just after take off causing him to crash and die. Humankind can continue because of sheer luck

Unless Meredith is long for Edith ABCD.........E!!!! lol

I'm guessing it's David or the other synthetic Ridley said might be in the film. Possibly a synthetic made by the Yutani corporation sent to spy or sabotage. The idea of a bio morphed synthetic ties in with the biomechanical look and feel of the SJ and did anyone notice in the trailer how the chair attaches itself the SJ? I think the SJ once seated becomes part of the ship.

the Figure we see at the beginning of the newly released full trailer is an Engineer or Space Jockey race...according to some movie theorists, are the ones who created all species and planets by terraforming....I really do believe that this alien figure has been affected by some type of unknown alien infection...It's puzzling, because we only see parts of the movie...But the Engineer's hand and arm looks to be infected with the same black veins as the character Holloway, who we can see is painfully changing into some alien species (in the trailer), while he is wearing his helmet...I cannot piece it together though...If the space jockey is getting affected, and then some of the humans are getting affected, then why is the Space jockey threatening to fly the derelict ship toward earth ?...Is he that pissed that the Humans stole some of the important 'Urns' containing DNA of all created life forms ?? (The Greek god Zeus punished Prometheus for stealing "Fire" from him to give to mankind)...Weland industries most likely wants the urns returned to Earth. OR has one Space Jockey gone "Rogue" because the "King's reign ended, because he died"

IT'S OBVIOUS THAT AFTER THIS NEW ALIEN INFECTION AFFECTS HOLLOWAY, AND OTHERS, THAT THEIR DNA IS MUTATING INTO A NEW ALIEN SPECIES....WATCHING THE NEW FULL EUROPEAN TRAILER CLOSELY, THERE IS A CLOSE UP OF A WORM LOOKING ALIEN PENETRATING ONE OFG THE CHARACTERS ARMORED LEFT ARM....REMINDS ME OF THE MOVIE "SLITHER", WHERE WORMLIKE ALIEN SPECIES SPREAD AND CRAWLS INTO THEIR BODIES AND INFECT THE HUMANS, THUS CHANGING THEM INTO ALIEN CREATURES THROUGH MUTATION.

I think it probaly is David and I think it's right at the end of the film.

It's clearly the Dark Lord Voldemort...

Think it might be David, right at the end of the film, not the start. A good jump-off for the sequal to the prequal (not).

The bald headed, bloodied, veins-moving-in-its-head, creature we see at the start of the trailer is Elizabeth shaw, after been infected and it'll be at the end of the movie... she look at here arm, like something new.

So that looked like a woman to you?

Somebody has to explain the saucer shape ship on top of water fall. When the albino guy looking at his hand the saucer is not in the scene any more. Could it be SJ drop the first human on earth then leave? May be this scene not related with moon or planet that Prometheus ship has landed.
