If you've seen any Alien movie, you'll be all too aware that human life (or synthetic's for that matter) doesn't mean much to shady corporation Weyland-Yutani. One mystery that has always left fans theorizing, though, is how much the company's executives really knew about the Xenomorph threat before sending Ripley and the rest aboard the Nostromo to LV-426.
Some are convinced they were just as in the dark as the crew (and that Special Order 937 was something they installed into every mission), others think they knew something was out there but underestimated what a grave danger it was, while others – largely down to its last minute decision to send Ian Holm's shifty robot Ash – are adamant it was fully aware of what Sigourney Weaver and co were wading into when they answered that "distress" signal.
