I have seen at least four different trailers for Noah so far — two that were shown at church conferences, and two that were released to the general public a couple of weeks ago — and if there is one thing that has been conspicuously absent from all four of those trailers, it is the gigantic fallen angels known as the Watchers. Oh, sure, I suspect that there are hints of those creatures in a few of the more cryptic shots in those trailers, but so far the studio has held back any bit of footage that might give us a clear sense of the role that they will play within the finished film.
Director Darren Aronofsky, on the other hand, has been teasing us with their presence in the film for a while, now. You might remember the “nephilim wuz here” picture, which didn’t really show anything, that he tweeted fifteen months ago. (In the Jewish apocrypha, the Nephilim are the offspring of the Watchers, but in Aronofsky’s film, these appear to be interchangeable names for the same basic set of creatures.)
