Every movie nowadays comes with a viral marketing campaign, to the point where a half-hearted one for an unanticipated can slip by without recognition. And that's probably why you had no idea Warner Bros. had mocked up a website showing the vague human awareness of the wider Abrasax. Called the Chicago-Wilmette Astronomers, the site itself is a somehow very informed account on the impending harvest, bringing the likes of Stonehenge and Devils Tower into the mythology. Teased on some character posters, the website is rather basic, but hints at the more complex mythology The Wachowskis had worked out before having to tone it down for a two hour movie, and is worth checking out for giving a look into the minds of those who witness alien activity and don't have their minds wiped. Overall, the trick was a failure, not really expanding over time like those for The Dark Knight or Cloverfield. A potential companion website, Harvest Truth, also popped up, but its legitimacy is unclear.
