It looks like Nick has even bigger problems in AMC's new clip, as he runs in terror away from someone… or could it be something?

Robert Kirkman and Dave Erickson's Walking Dead companion series takes place in Los Angeles at the beginning of the zombie apocalypse.

Nick's mother Madison (Kim Dickens), his sister Alicia (Alycia Debnam-Carey) and Madison's boyfriend Travis (Cliff Curtis) are all central figures in Fear the Walking Dead.

Erickson has promised that Fear the Walking Dead will have its own unique identity, separate from sister-series The Walking Dead.

"There's a bit more of a slow-burn to the story. We don't get to a point where we're actually in a full-blown apocalypse until much later in the show," Erickson said.

"[Fellow EP] Robert [Kirkman] wanted to really dwell on what it's like to [commit] a violent act - especially in our world, because it's so early, and our walkers are fresher and far more human.

"It's [emotionally] difficult to kill them, even when somebody's coming after you... In terms of emotional tension, when we put one of our characters through a moment where they have to commit some brutality to defend themselves or others, they'll suffer for it."

Executive producer Greg Nicotero has been dismissive of a potential crossover, telling Digital Spy that there is "no intention of crossing over the two shows".

Fear the Walking Dead will premiere this summer on AMC, and will later stream exclusively on Hulu in the US. The series debuts in September in the UK exclusively for BT customers.
