Empire Magazine has recently interviewed Prometheus writer Jon Spaihts about his involvement with film, a possible trilogy and the unused ideas that were included in his early drafts. You can read the whole thing here.
“We tried different paths in that way. We imagined that there might be eight different variations on the xenomorphs – eight different kinds of Alien eggs you might stumble across, eight kinds of slightly different xenomorph creatures that could hatch from them. And maybe even a rapid process of evolution, still ongoing, in these Alien laboratories where these xenomorphs were developed. So Ridley and I were looking for ways to make the xenomorphs new.”
