We're really creeped out by the latest couple of teasers for BBC America's Intruders. Centered around a secret society searching for immortality by possessing the bodies of others, we're not sure what to expect from this series. But we are happy it's got Life on Mars and Doctor Who's John Simm!

From writer & executive producer Glen Morgan (The X-Files), this series is based on the novel by Michael Marshall Smith. Has anyone here read Intruders? Because we're dying to know more. Here's the official synopsis:

INTRUDERS is about a secret society devoted to chasing immortality by seeking refuge in the bodies of others. A contemporary, chilling, paranormal tale set in the moody Pacific Northwest, INTRUDERS spins a fascinating and complex web of drama. As strange, apparently unrelated events start happening, multiple story-lines — a missing wife, an assassin covering his crimes, a child on the run — begin to intertwine to reveal a conspiracy that will forever change our understanding of human nature.

And here's a previously released clip that actually shows the whole body possession thing.
