Bit late to the party here as this trailer seems to have been one of the most widely shared trailers of recent years.
But anyway, for completeness, here it is.
The use of a cover of “Nature Boy” by Nat King Cole in the soundtrack is interesting. Of course that was previously used in the opening sequence of Moulin Rouge and has a haunting feel to it in both instances.
Michael Fassbender’s David appears to be the “very strange enchanted boy” in the Alien Covenenant trailer, and his motives seem unclear as he watches on as someone receives a facehugger face-hug.
The movie is out on 19 may 2017.
