Im guessing they will be using alot of the celtic heritage architecture, and scott will include some form of digital manipulation too here and there, to make the set appear more alien, similar in respect to what he did with the roman coleseum in gladiator. Prometheus is going to see something never ever seen before, by giger that is going to be so messed up especilally mixed with celtic architecture, it will be engraved in the viewers memory. This film will be a return to top form for scott. Scott films in Scotland, how ironic lol
