Our first couple glimpses of Intruders, BBC America's new series about a secret society that seeks to attain immortality by possessing other people's bodies, were seriously spooky. This new, extended trailer continues the trend. Oh – and the show now has an official release date!

The show, which is based on Michael Marshall Smith's novel 'The Intruders' and is being written and produced by The X-Files' Glen Morgan, is set to premier August 23 at 10/9 central. We're not entirely sure what to expect, but with Morgan at the helm, and talent like John Simms and Mira Sorvina signed on, we're excited to see if this show can match the depth and scope of BBC America's current breakout success, Orphan Black.

Here are more details from BBC:
