The Walking Dead star Andrew Lincoln says season 8 finale is 'unbelievable'

The Walking Dead season 8 finale in three letters? "WTF," says star Andrew Lincoln.

Chatting with The Hollywood Reporter, Lincoln, who portrays the down-on-his-luck-but-not-totally-defeated Rick Grimes in the post-apocalyptic zombie series, previewed the upcoming season 8 finale, entitled "Wrath." Weighing in on what's in store come April 15, Lincoln stated, "I can [describe it] in three letters: WTF. It's unbelievable."

The forthcoming final episode of The Walking Dead's eighth season brings the tense conflict between Rick's Alexandrian army and Negan's (Jeffrey Dean Morgan) not-so-merry band of Saviors to a head — then ends it for good. Those who have been keeping up with the Robert Kirkman and Charlie Adlard-created Walking Dead comic book series have a rough idea of what the visceral swan song of the All-Out War will entail, but those same fans should still watch with wary eyes, as the series hasn't exactly remained 100-percent faithful to the written source material. Carl's (Chandler Riggs) death earlier in season 8 was a massive deviation from the comics on which the show is based, so there's no telling what the minds behind The Walking Dead have cooked up for the final episode.

The Walking Dead showrunner Scott M. Gimple, who ends his four-year run as the proverbial leader of the show circus with the upcoming finale to take on a larger role overseeing the greater Walking Dead franchise, kept a tight lip on how closely the episode follows what's depicted in the comics. 

"If I said it mirrored [the comics] super closely, that would provide a lot of answers. Aspects of the comics are there, and then there's some other stuff in there and some big left hand turns to the comics," Gimple stated. "It's totally the same, and no it's not at all the same, and it's completely different."

There is, however, one thing fans will definitely get in "Wrath": an answer to the bloody shot of Rick against the tree. Gimple noted that the finale "will indeed" provide closure in that regard and a sense of resolution in general. 

"It closes down every character's story pretty much in some tragic ways and in some sad ways, and even some hopeful ways to a degree," Gimple concluded. "There's closure, in every iteration of what that means, in the finale."

The season 8 finale of The Walking Dead will air on Sunday, April 15 at 9 PM ET on AMC.
