A month before "The Walking Dead" Season 7 premieres, Greg Nicotero talked about who Negan kills during the last season's cliffhanger episode.

Nicotero, the occasional director and the mastermind behind the horror make-up effects of the walkers in AMC TV series "The Walking Dead," was interviewed by Entertainment Weekly "about the challenges and keeping under wraps" of the show.

Nicotero said they have gone to "pretty significant lengths" and shot scenes on the backlot to avoid public photos and people climbing trees.

Talking about Season 6 ending on the huge cliffhanger episode, "I'm really proud of the episode, and I really love it, and I was a little surprised that people had that reaction to it."

"So I feel like starting Season 7 it's like, we'll give the audience a better emotional place with which to process what happens and really be able to understand how it changes every single person moving forward," he added.

During the interview, the director explained the point of the upcoming Season 7, saying, "So there was a reason behind it. It certainly was not just about who Negan kills."

However, his interview made a little controversy when the executive director mentioned "deaths."

"I don't think we would have changed anything. I would have still supported doing it the way that we did it, because of the fact that the story doesn't end there. If we would have shown the deaths, then they wouldn't have felt our characters in season 7 the way they need to. And the thing that I think a lot of people will get out of it is how that moment changes the entire makeup of our universe within a split second. And it's that moment that launches our entire season 7 into that direction," he said in the interview.

Since "The Walking Dead Season 6" ended, there were a lot of theories about who Negan killed among Rick's group.

AMC's TV series "The Walking Dead Season 7" will be released on Sunday, Oct. 23.
