David and P,Weyland scene

I did remember that old news ...that we forgot ... in Spain were filmed ( or probably filmed elsewhere , they did the booking but we dont know if they went there ) some scenes that were involving ONLY Fassbender and Pearce , in a big water tank in south spain . That rumor was never confirmed but was from a reliable source ( i think the same that said that PEarce was in heave prohestetics ) . Today we know that David and Peter Weyland have a sort of relactionship so that old rumor return to be very interesting .
