Am excited about this, but...

So, I've been keeping an eye out for the trailer for Whit Stillman's movie Love & Friendship, an adaptation of Jane Austen's novella Lady Susan. Sadly, all I can find is this cast interview, despite the fact that the (presumably complete) film was screened at Sundance back in January. Why so slow, Stillman? Also, why did you choose a promotional picture for your film's website that renders both Kate Beckinsale and Chloë Sevigny totally unrecognizable?
