'The Walking Dead' spin-off 'Fear of the Walking Dead,' which was announced earlier this year, is finally taking shape. The first trailer of the upcoming horror television series on AMC was released recently and from the look of it, the show is likely to be as popular as the original series.

Quoting LA Times, Latin Post reports that 'Fear the Walking Dead' is a prequel series that will delve into the beginning - the place in time where the zombie uprising is said to have started officially. The series is set in Los Angeles.

According to the report, the series will show the period when Rick Grimes (Andrew Lincoln) was shot in the line duty, prior to waking up in the hospital and discovering the zombie apocalypse.

Although the teaser-trailer of 'Fear the Walking Dead' does not reveal much, the introduction to the series is certainly quite amazing, as it displays a great sense of the looming doom that featuring what seemed to be the series lead character Nick (Frank Dillane) escaping from something.

While 'The Walking Dead' Season 5 will soon be aired on AMC, this companion series is also scheduled for an August 2015 premier on the network channel. Robert Kirkman is the showrunner of 'Fear the Walking Dead.'

According to a report in Entertainment Weekly, Nick's sister Alicia (Alycia Debnam-Carey) joins him in the upcoming series. Recently, Kirkman offered some insight into these two characters.

In an interview with Entertainment Weekly, Kirkman said, "Alicia is your atypical teenage girl. She excels at school. She's on her way to college. She's very self-sufficient. She's very self-reliant. She's kind of the model student and the model child."

On the other hand, Nick is just the opposite of Alicia, Kirkman pointed out.

"In the face of that (Alicia), we've got Nick - played by Frank Dillane - who is pretty much, a parent's worst nightmare," Kirkman said, adding, "He has flunked out of college, had a lot of trouble, got mixed up in some bad elements, and is definitely the problem child. And it's exacerbated for him to be next to this perfect sister who seemingly doesn't have anything going on in her life that is negative. But that's not really the case, that's just his perception. So you have these two siblings that are very much at odds with each other."
