It's nearly time for The Walking Dead to return to our screens, and show bosses have hinted that the fourth season is set to be the most explosive yet.
The first official teaser trailer of the hit US zombie horror series has sent fans into overdrive.
Just when the group thought it was safe back in the prison, a new invasion of 'walkers' and a mystery threat have infiltrated their once safe zone.
Comic book creator Robert Kirkman explained that much of the graphic novel's plotlines will be incorporated into the television adaptation.
“There’s some really, really cool and big stuff that people have been expecting, or that people have been anticipating from the comics, that will work into season four," he explained.
"To give a hint, I will say that we do have Tyreese and Rick, who are now united, which is a big moment for the comic book fans."
And he hinted that the main character, Rick Grimes (played by Andrew Lincoln) will take a very different turn over the coming episodes.
“It’s going to be different in a lot of ways," he added.
"We’ll see a very different Rick Grimes for one. His experiences against the Governor and with the various things that happened to him in season three are informing his character in huge ways.
"We’ll see a lot of familiar elements from season three: we’ll see the prison, Rick and his group are still in the same place but those elements are all going to be radically different.
"This is the moment where Rick takes a turn; he’s no longer going to be pushing people away, he’s no longer going to be doing what ever he can to protect these people in ways that hurt other people.
"He’s not going to be the guy who would leave that guy on the side of the road — the backpack guy in Episode 12.
"He’s letting the people of Woodbury in and trying to tell Carl that these people are like us, you have to be open to this and the only way to survive in this world is to have people and be in a community. That’s going to be a big part of season four.”
The show airs first on American network AMC on October 13th and is set to air on Irish screens on RTE Two later this year.
