Tom Perrotta's 2011 novel, The Leftovers, has a chilling and provocative subject — when a Rapture-like event claims most of the world's population, those who are left behind have to wonder what happened, and what do they do now? HBO has adapted the book into a series set to debut June 15, with Lost creator Damon Lindelof as a show-runner. Until today, we've only had a couple brief teasers. Now the full-length trailer is here to give you goosebumps. Justin Theroux stars alongside Liv Tyler, Christopher Eccleston, Amy Brenneman, Michael Gaston, and Ann Dowd. In case you're wondering, the song is "Retrograde" by James Blake. If you read the book, pipe up: does it look like what you imagined?
