Watch the First Four Minutes of The Walking Dead's Thrilling Return

The hugely popular zombie drama The Walking Dead returns to screens on Sunday (February 14), and AMC have released the first four minutes of the next episode. Check it out below:

Earlier this week, star Andrew Lincoln spoke to EW about what fans could expect from the second half of season six. "The pace quickens a lot in the back eight [episodes]," he said. "It jumps up a gear, maybe two gears, and we move very, very quickly. A lot of things happen in quick succession that propel us towards a very thrilling finale.

"The scale of it is astonishing. And [director] Greg Nicotero and our brilliant crew put their bodies and everything on the line to get it shot. It was all night. It's absolute mayhem. I think it's going to scare some people."

In November it was announced that Negan, the notorious club-wielding villain from the Walking Dead comic books, had been cast and would appear towards the end of the current season. Watchmen star Jeffrey Dean Morgan will take on the role, and is expected to become a series regular in season seven.

The Walking Dead season six returns to AMC on February 14, 2016.
