Jon Spaihts interview with Empire. Definitely worth reading IMO.
re: double dipping - iirc there was one part from the trailers I've not seen anywhere else - with Shaw and Holloway at the dig site. So I guess it's possible..
And wasn't Peter Weyland originally meant to be in the background of the Fifield attack scene?
The engineer doesn't look at the books in the extended scene - he walks in and runs his hand through the chandelier - he seems as amazed with that as David is with the map holograms...then Shaw hits him with the axe - a LOT - then she unleashes the squid.
