The season 6 premiere of AMC's "The Walking Dead" is going to take fans by surprise, teased actor Andrew Lincoln, who plays Rick Grimes in the zombie apocalypse drama.

The 41-year-old actor told Entertainment Weekly that there will be more walkers and more action in the upcoming season, which will return on 11 October.

"I think that Episode 1 is not something people are going to expect, I certainly didn't when I read it. And when we filmed it, it just grew and grew and it got deeper and deeper," Lincoln said, adding that a couple of episodes in the season are some of the best he has seen.

The actor also praised showrunner Scott. M. Gimple for spinning different storylines together.

 "There are more walkers than we've ever faced before. I think the storytelling is astonishing. Scott has kind of picked up very much where we left off and he's spinning 18 principal storylines in an incredibly complicated and cool way," Lincoln added.

While not much has been revealed about the premiere episode, director Greg Nictotero revealed to the publication that the season will pick up in the middle of an action sequence and there will be slight time jumps.

In yet another interview, cast member Norman Reedus, who plays Daryl, teased that conflict between Rick and Morgan will split the group. He also noted that one key member will bid adieu from the show in season 6.

In an interview with MTV, Reedus was asked which deceased character he would like to bring back on the show, and he immediately named Glenn, who is still alive.

Although a good number of fans are worried about Glenn's fate, Reedus' statement has also generated a lot of intrigue, as in Robert Kirkman's comic book series, Glenn is killed by Negan.

If Glenn indeed dies in the television adaptation, fans won't have to wait long to see Negan, who is one of the most notorious villains in "The Walking Dead" series.
