Neil Marshall on Alien and Prometheus:
Despite all I’ve said above, the ALIEN is basically a predator, and that’s something I can get my head around.
The SPACE JOCKEY, on the other hand, is entirely unfathomable. Has it grown out of the chair? Has its “nose” apparently connected to its body in such a way it cannot move? It is, to my mind, something utterly and completely alien. Imagine my crushing disappointment to find out, all these years later, that it was not some inscrutable alien being after all, but was, within the context of the story, just a man in a suit! Painfully ironic
