Director Ridley Scott is currently in post-production on Prometheus, his upcoming sci-fi thriller that may or may not have a connection to his 1979 classic, Alien. If these new spoiler-laden photos actually are from Prometheus, which reportedly come from someone in the art department, the Alien connection is definitely there. Take a look at these "monster mask" photos below.
These models are supposed to be for, "the alien" in Prometheus, which seems to be a hybrid of the Space Jockey and Xenomorph designs from Alien. This mask is designed to be worn by an actor, and the insider also claims this creature is achieved by practical methods.
"The creature featured in Prometheus has been executed with very little CGI planned."
