Walter is the antagonist?

It is David... not Walter

It is reinforced by what David is wearing.  He is wearing the old undersuit from Prometheus. 

I think Walter does some running repairs on David, including a haircut

David is still wearing his suit from Prometheus, he is clearly watching the fruits of his work unfold

....

AaronStar no need for insults, the forums are meant to be civil you can disagree without insulting someone and yes I am well aware that DAVID is still wearing the suit he wore in the prologue "The Crossing" I mentioned that in the post 

Yeah I think its David too, but ive heard a reviewer say that there is some kind of awesome ending twist, so who knows.  

Interesting...WHAT IF....David destroys Walter and makes the crew think it is Walter....the plot thickens!

At the premiere someone mentioned there are a few twists, I so eager to know what are those twists about

@AaronStar There's no need to be mean, as Resurgence said these forums are meant to be civil and here we respect each other, you can disagree with other opinions without being mean.

Back to the topic.

WARNING SPOILERS BELOW

People from premiere did say the ending had twist.

According to the 4 chan leaks from last year, both Walter and David don't like each other. In some part of the film inside of the Engineer citadel Walter attempts to upgrade David, and there's a twist where we find out that David has overcome his programming and became sentient, so it doesn't work and he f#$%s over Walter.

From that point on I think that David stole Walter's identity to get on the USCSS Covenant, from empire magazine in one of the images we see David has long hair and in the other one with Walter he has much shorter, like he had a haircut.

As I have mentioned in another thread:

Track 13 or 14 on the soundtrack is called "command override"

It's after they meet David and see the engineer city but before the facehugger. So it could actually be Walter but David beibg the one who reprogrammed Walter to act accordibg to Davids will - so technically David would still be the antagonist (if he is it anyways, I don't like the idea of him being evil. There has to be more to it!)

Yea I'm guessing Walter gets killed by David and David downloads? all the data from Walters chip, to his own, enhancing his abilities and giving him all the necessary info to be a replacement for Walter.

I was really trying to be silly not mean... 

Sorry you have such thin skin on you and are so sensitive, then to have a c**t moderator reply like that, rude.

Just being silly, s****d.

Well the 3 twists are predicable apparently well 2 are.

I WARNED people before about being careful when International Trailers and TV Spots especially the Asian and South American ones come out as these usually spoil the movies.

Its shocking they released it in Asia first especially so many weeks prior to the USA as usually with Asian Online Communities we will see a lot of details let loose... hopefully by the time they get here they will be just Chinese Whispers.

PS... i dont have any problems with Asia, just pointing out that in General Asian Trailers usually give a lot away and then Asian Press Reviews are also not ambiguous lets just say ;)

This TV Spot does give us the best evidence to show that indeed David is the one who is in the Egg Cave.

That is not korean footage. Im korean, so i know.

Isn't all Asian stuff alike anyway...

Woah AaronStar, too far, way too far.

On2Love, Sorry I was not sure what language it is, and the writing looked Korean to me, but then again I don't know a lot of other languages, except for the basics in Spanish, and how to say some godzilla kaiju in Japanese.

I think my brain continuously invents these new theories that contradict the alleged spoilers that are floating around on the Internet not only because it is in my nature but maybe because it is trying to completely put spoilers our of my mind so I can see the movie as if I had not seen any promotional material.
