Well, isn't this Weyland?

no, its milburn (see the glasses?), telling fifield, " calm down, im just gonna see if it wants a bite of my arm."

He does look like Guy Pierce though...may be he's telling David in the back 'that brown stuff in the urns smells funny - let's take the juggernaut home and analyse it' as someone has already suggested hinting at original greek myth

does resemble guy pearce in this shot, but its not guy pearce, its the milburn character. weyland doesnt wear glasses, and the shots we've found that seem to be him show him barely able to stand up on his own, let alone tell a guy like fifield "i got this". and the other guy isnt David, its Fifield, you can see the mohawk. this is when the little worm shows up and checks milburn for tonsillitis.

ok, agree. what's interesting about this scene though is that urns seem to be used/opened which led me to think it might be from later on in the movie...

Definitely Millburn & Fifield ;) ... Also ... this doesn't look like 'THE' BIg Head room ... it looks like a different one and very messy ... hence why there's nasties crawling around ... looks like an old derelict building site type of place ... if you get my meaning ...

he can be standing next to head's chin, just different lighting conditions...

so who opened them? Burke is on the ship too?!! ))

one thing that i hadnt noticed before, is that ALL the urns seem to be spilling over. if each one contains an organism, then those guys are in the wrong room.

If it were Weyland (assuming Weyland is with the crew based on some footage we've seen), I don't think he'd be standing upright like that. I've noticed that the "Old Guy" in the first teaser seems to be standing with his torso lowered somewhat.....obviously this guy has aged to the point where he can't hold up as well as his younger counterparts, not to mention that, if I remember correctly, the Old Guy is escorted and guided as to where to go, or something to that extent (the escorts act as handlers I guess). The guy in the foreground in the image is probably Milburn, easily recognizable by the glasses, though the shading hide his overbite (a noticeable trait in Harold Green from The Red Green Show, hence me comparing Milburn to Harold Green, lol).

it doesnt resemble Pearce, it resembles Spall.....doesn't look like the big head room? Even though there is a big head at the right of the image?

Yep...that's Mr. Glasses Dude. You know, the one who has hammerpede souffle for breakfast?

And snakes in his spaghetti.

Sorry I'll rephrase that ... I reckon they're NOT in THAT Big Head room that we know so well ... I reckon they're in 'different one' ... because in most of the footage, that I've seen, with David looking around the original big Head room, the urns seems to be intact and not leaking ... ;) ...

No one likes a leaky urn...

hmmm... looks more like wc onboard prometheus was too far away for someone

so there are either multiple rooms or something has caused the spillage, simple

Well there are FIVE TEMPLES to choose from ... ;) ... Do we only see ONE temple as a massive hologram in Prometheus's control room ... and what about those under ground tunnels leading off to nowhere ... I reckon they interconnect to each temple ... possibly ...
