The HEAD - why in bondage

I think the markings are symbolic rather like tribal scars and similar in theme to markings on the giant stone heads found in Oceanea/Pacific islands.

@mogy79 I've been wondering about the suits as well. Could it have something to do with the filming in 3D? Some weird technical reason the suits have to look like that?

I think the ´bondage´ are rather mason marks, it should only show that its a very ancient sculpture, thousands of years old..therefore the huge crack in front etc..

Well as far as the suit difference in prometheus vs alien the promethus crew was on a slick state of the are exploration vessel so the suits would reflect that, the nostromo was older and used looking like it had already made lots of deep space trips so the suits would be more that speed

NO IT'S NOT BONDAGE, THERE'S A LINK IN THIS FILM WITH THE ERIC VON DANIKEN BOOKS, "WAS GOD AND ASTRONAUT", WERE A LARGE AMOUNT OF THE, ALLEGED, EVIDENCE CAME FROM SOUTH AMERICA . THERE ARE SOUTH AMERICAN, PARTICULARLY AMAZONIAN, THAT DECORATE THEMSELVES WITH DISC INSERTS, TATTOOS AND GUT-TIES, PARTICULARLY ACROSS THE BRIDGE OF THE NOSE. THE HEAD FEATURES TATTOOS AND THE TIES, THE EAR-LOBES LOOK ENLARGED ALSO. THE HEAD ALSO HAS A RESEMBLANCE TO THOSE ON EASTER ISLAND, ACCEPTING THOSE ARE IDEALISED THERE IS DEFINITELY A RESEMBLANCE. YES, THE CRACK AT THE SIDE OF THE HEAD'S TEMPLE IS CERTAINLY A TRIBUTE TO FRANKENSTIEN
