SJ Inconsistency Between Alien & Prometheus

The 'skull'/'helmet' on the medical table in the trailer is partially obscured, making it seem smaller than it really is during that brief glimpse. But I reckon it's the same one that we see in this pic here, and this certainly seems plenty big when compared to the 2 human heads inspecting it, considering we're only seeing the top-half of it - http://imgur.com/y9tZk.jpg So I have no worries about the scale not matching the ALIEN one. And the 'big, bald humanoid' in this shot here is an unknown size at the end of the day, so I also have no worries that the 'chair' will be similar in scale to the original one in ALIEN either. We don't 100% know that this guy will be the one to sit in the 'chair' eventually, but if he *does* put a 'helmet' on, I've no doubt it looks in scale with what we saw in ALIEN. What I *will* be bothered about though, is if this PROMETHEUS 'chair' and 'Derelict' are supposed to be the exact same ones seen in ALIEN, as there are just so many differences in the actual design details of these between the movies...and these have been brought up in the likes of these topics - 'Continuity Errors' in PROMETHEUS Designs?' - http://www.prometheus-movie.com/community/forums/topic/915#7610 Two Different Space Jockey Vessels...Or The Same One? - http://www.prometheus-movie.com/community/forums/topic/537 But as some of these differences seem so distinct on the PROMETHEUS 'chair' and the 'Derelict', I'd be surprised if it turns out to be the actual version seen in ALIEN. I hope I'm not wrong.

Indeed these Jockeys look smaller than they should be if we look at Alien, and if theyre bigger it is more dramatic and original. I stopped being concerned about anything, just going with the flow, trying to have as few expectations as possible. I think the movie will be more enjoyable that way. But yea in Alien, if we stood up a human and a Jockey next to each other, the human would reach to the jockey's knee or a little above, right? So they better come up with something here because it will look pretty silly if theyre much smaller with no reason.

Could be there are just different sizes within that species.

I agree with spacejock. Just taking in everyones opinions and comments and will enjoy the movie when it gets here. But the "helmet" that we see being scanned could be a different size than in alien. So far the chair we see coming up threw the floor has no humans next to it. So we dont know exactly how big it is just yet. The space jockey who dies in Alien sould be much bigger than the helmet being scanned.

There is a human to the right of the screen as the chair rises......

no, you're a fool as is anyone who belives this. it's the same size. do more comparisons if you don't believe me. and the space jockey "head" is a skull, stupid. of course it's smaller. it has cranial suture marks. just use your eyes and your head. my god.

Thats not a human next to the chair in the trailer....what is it exactly...not sure

U know, the cranial suture marks are only present on that fan made sculpture that leaked a few days ago. Hes just saying it still should be bigger as a helmet/skull/whateverdafuq it is, compared to the skull dallas is looking at up close in alien. Maybe it is only optical illusion and there isnt a great inconsistency?
