Check out a new look at the new additions to the cast of The Walking Dead, which will return with its sixth season on October 11th; in case you missed it, watch here the first trailer.

As revealed by EW, Merritt Wever will portray Dr. Denise Cloyd, whose role as a medic becomes critical in the community of Alexandria after the death of Pete. Ethan Embry will take on the role of Carter, who will serve as a composite of different people from the original comic; here’s what Scott M. Gimple said about the character: 

“Ethan plays a combo of a few characters that we actually haven’t hit yet or weren’t able to hit in other characters. He is an Alexandrian, and has been there the whole time, just quite busy.”

As previously announced, Corey Hawkins will be playing Heath; the showrunner had this to tell about him:

“He’s terrific and I’m so excited to see him bring Heath to life. It’s been fun and he dove in with both feet. He’s tough and skeptical when the cameras are rolling, and then when they’re off he’s just like a goofy fan. He’s really, really excited to be there."
