'The Leftovers' Will Premiere June 29 on HBO (Trailer)

The debut date for The Leftovers has changed. The series begins its ten-episode season Sunday, June 29 at 10 p.m. ET/PT on HBO (not June 15, as originally announced).

From Damon Lindelof (Emmy winner for Lost) and acclaimed novelist Tom Perrotta (Academy Award nominee for Little Children), The Leftovers is based on Perrotta's bestselling novel of the same name. The drama series takes an original look at The Rapture... because it's not entirely clear The Rapture happened.

Justin Theroux, Amy Brenneman, Christopher Eccleston, Liv Tyler, Charlie Carver, Max Carver, Carrie Coon, Ann Dowd, Michael Gaston, Emily Meade, Annie Q, Margaret Qualley, Amanda Warren and Chris Zylka star.

On Sunday, the first trailer for The Leftovers aired on HBO prior to a new episode of Game of Thrones. Watch it below:

Amy Brenneman to Guest Star on REIGN as Mary, Queen of Scots' Mother

Catherine de Medici has met her match! Amy Brenneman (JUDGING AMY, PRIVATE PRACTICE) will make a guest appearance on REIGN as the mother of Mary, Queen of Scots in an episode to air in Spring 2014.

Brenneman will play Marie de Guise, Mary, Queen of Scots' mother and the acting regent of Scotland. Beautiful, brilliant and cunning, she returns to French Court after years apart from her daughter. She faces off with Catherine de Medici, the woman to whom she traded her child for Scotland's protection, and the two mothers will conspire against young hearts, fierce desires and dark warnings for the purpose of achieving their own ends.
