The First 'Fear The Walking Dead' Trailer Is Here, And Totally Terrifying

Finally, we got our first full look at “Fear the Walking Dead.”

The first trailer for the “Walking Dead” companion series debuted at San Diego Comic-Con on Friday, and it’s pretty terrifying. Remember, the spinoff takes place before the events of “The Walking Dead,” and shows the zombie outbreak as it begins to happen. Kim Dickens’ Madison and Cliff Curtis’ Travis, along with the rest of Los Angeles’ citizens, are first introduced to the possibility of zombies in the trailer, and it’s too startling for them to even believe. Here’s what else we learned about the new show:

The show covers the period of time when Rick was in his coma, “how people adjust to the apocalypse when it comes down on them.” #FTWD

Timeline-wise, by the end of Fear the Walking Dead’s first season, we still won’t be to the end of Rick’s coma. @SDCC

Before this, we only got a few brief teasers and promos for the new prequel series. In addition to Curtis and Dickens, the new spinoff will star Frank Dillane, Alycia Debnam Carey, Elizabeth Rodriguez, Ruben Blades and Mercedes Mason. Expect the new show to have lots of “psychological tension,” as promised by showrunner Dave Erikson.

Before the new “Fear” trailer debuted on Friday, AMC also released the first trailer for “The Walking Dead” Season 6.

“Fear the Walking Dead” premieres on Aug. 23 at 9 p.m. ET on AMC.
