Justin Theroux gives his take on The Leftovers series two

In season one, The Leftovers established itself as one of the most engaging and befuddling shows on television. Based on the novel of the same name, by Tom Perrotta, the series follows a population struggling to come to terms with the mysterious disappearance of 140 million people.

In a plot twist worthy of the show's creator, Damon Lindelof - who made the hugely popular Lost - season two opens in a whole new setting: a small town in Texas that hasn't suffered a single disappearance. Lead actor Justin Theroux (right) tells us what viewers can expect.

"I think that's the appeal of this show; the questions are profound and some of them are like, 'What's the point of life?' I don't think we're going to be able to wrap that up in the finale. I think sometimes it's just Damon putting the questions out there and letting the characters walk around them. That's interesting because it's what we do in our personal lives."

"The scripts are gripping because he writes in a very fast-burner style and you can't help but keep turning the page. Only when I really get hung up on something will I call Damon and say, 'I don't know what I'm doing. Help me out here.' Really you just have to play the not knowing."

"Damon was very upfront about not knowing if there needed to be a season two. He knew he didn't want to go back to [fictional] Mapleton [the New York state setting of the first season]. I think they only wanted to do an idea that would open the show up, not just visually but emotionally, and allow them to explore something else. By the end of season one we were all tired of the loss."

"In New York, when you're done shooting you have another thing happening. But when you're in Austin, there's not that much happening. Even though Austin is wonderful, it strips away a lot of the distractions and it all becomes super about your job. It gels things in a nice way because we're all in the same boat."
