EXCLUSIVE: The Sudden Departure event at the heart of the mythology of freshman HBO drama The Leftovers is spreading to the cast. I have learned that a large portion of the fourteen regular cast members in Season 1 — virtually all in supporting roles — won’t be returning in Season 2 as the series is undergoing a creative reboot, moving the setting from the fictional town of Mapleton, New York to a new location.

I hear locked in to come back are most of the leads — star Justin Theroux, his onscreen family, estranged wife, played by Amy Brenneman, and children Margaret Qualley and Chris Zylka, as well as Carrie Coon, who plays Theroux’s love interest, and Christopher Eccleston, who portrays former reverend Matt Jamison. As Season 2 is still being mapped out, I hear things are still in flux and there is a possibility for a couple of more regulars to come back — I hear Liv Tyler is returning and Ann Dowd is also likely to continue — with others potentially making appearances as guest stars. Leftovers‘ Season 1 regular cast also included Emily Meade, Amanda Warren, Michael Gaston, Max & Charlie Carver and Annie Q.

Created by Damon Lindelof and Tom Perrotta, Leftovers was based on Perrotta’s book about the aftermath of a Rapture-type event that causes the sudden disappearance of 2% of the world’s population. With the series burning through all of the source material in the first season, I hear the producers liked the story opportunities that would come from exploring the world beyond Mapleton.
