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?
