During an interview, Robert Kirkman claimed Norman Reedus (Daryl) originally auditioned for the part of Merle Dixon. He was rejected, but his audition so intrigued the show-runners, that they created the part of Daryl just for him.
In an interview on National Public Radio, Steven Yeun (Glenn) said that his parents (who emigrated from South Korea as adults) watch the show faithfully, but do not always understand the nuances of the English used in it, so they get a bootlegged version with Korean subtitles. Yeun also said that his father once asked him to thank Melissa McBride for saving his life. Even though Yeun reminded his father that it was all make-believe, Mr. Yeun insisted that his son should thank her, which he then did.
Among the common nicknames for the walking dead that are shared in different groups, are "Walkers", "Lamebrains", "Biters", "Rotters", "Skineaters", "Lurkers", "Roamers", "Geeks". The term "zombie" has never been used.
Originally, the characters of Lizzie (Brighton Sharbino) and Mika (Kyla Kenedy) were going to be cast as different gendered twins, with Mika being a boy named Mike. However, after Kyla Kenedy's audition via Skype, they scrapped the idea, so they could cast her.
Between seasons one and five, Carl Grimes has only aged twice, from age twelve to fourteen. However, Chandler Riggs will be eighteen years old when season eight progresses. This means there could be some sort of time jump (seen in the graphic novels) to ensure that the actor isn't too old for his role.
According to Norman Reedus, he accidentally incited a small panic among The Walking Dead (2010) fans when a photo surfaced of him sporting a prosthetic dismembered stomach. This photo does not spoil the end of Daryl Dixon, but rather Reedus' character in Pandorum (2009).
During filming of season six, Alanna Masterson (Tara) was pregnant with her first child, a baby girl, who was born on November 5, 2015. Eagle eye viewers will be able to spot some subtle cover-ups during full length shots.
Deanna, the leader of Alexandria, has the biggest character change from the comics. The leader in the comics is actually a man named Douglas. Deanna's husband, Reg, is named Regina in the comic, and is Douglas' wife.
In an online interview, it was revealed that Frank Darabont envisioned having several self-contained episodes that would not continue the main story. One such episode would have been the season two premiere. It would have involved Sam Witwer (who Darabont used in The Mist (2007) and played the tank zombie in the series premiere) as a soldier in a Black Hawk Down (2001) styled Atlanta. Witwer's character would have encountered several of the cast before being bitten and locking himself in the tank.
The actors portraying the walkers are actually more talented than one might think. They have to walk and sound like the creatures, while also avoiding breathing too much. They also have to jolt their limbs to take bullets realistically, and effectively pretend to eat fake human flesh and meat.
In late 2015, there was a casting call for a character named Orin. A description for this character says that he is smart, brutal, inappropriate, hilarious, et cetera. It is rumored that he will show up at the end of season six. This character is most likely Negan.
In season three, the beginning of the first and last episodes have the same camera sequence. The Walking Dead: Seed (2012) begins with a close-up shot of a walker's eye, with the camera slowly zooming out, while The Walking Dead: Welcome to the Tombs (2013) begins with a close-up shot of The Governor's eye, with the camera slowly zooming out.
In 2009, Thomas Jane agreed to play Rick Grimes, because of his friendship with showrunner Frank Darabont, but when he signed with HBO for another series, he said no to Frank. He says he regrets saying "no" to the role.
Jon Bernthal and Michael Rooker are involved with Marvel. Bernthal plays Frank Castle, a.k.a. The Punisher, on Netflix's Daredevil (2015), and Rooker plays Yondu Udonta in Guardians of the Galaxy (2014) and Guardians of the Galaxy Vol. 2 (2017).
In the comics, Morgan Jones dies in the Alexandria Safe Zone, where a herd of walkers break down the walls, and attack survivors. This attack is foreshadowed in the season five finale titled "Conquer", where Morgan saves Daryl and Aaron from a mob of walkers, who come out of cargo trucks. Later in the episode, the wolves are seen leading the same walkers back into the trucks.
Creator Robert Kirkman addressed the beginning of this and the comic series as being strongly similar to that of 28 Days Later... (2002). According to him, it was "a complete coincidence. I saw '28 Days Later' shortly before the first issue of Walking Dead was released. That first issue came out in October of 2003 and 28 Days Later was released in the States in June of 2003. So we were working on our second issue by the time I saw it. It was going to be a matter of somehow trying to restage the entire first issue, because it was a very similar coma opening. I made a decision-which I pretty much regret at this point-I said, 'You know what? It's so different (from that point on), I will probably never hear anything about this.' And I was wrong."
Sonequa Martin-Green originally auditioned for the role of Michonne. While she was unsuccessful, producers liked her audition so much, that they created the role of Sasha Williams for her (the character does not appear in the comics).
Basically, when recurring cast members are promoted to series regulars, their names are added after the original series regulars in the opening credits. However, this is is not the case of Norman Reedus and Lauren Cohan, who are credited before Chandler Riggs who has been a regular since the first season.
Christian Serratos (Rosita Espinosa) has the most appearances out of all the series regular cast for season seven, featuring in eleven out of sixteen episodes. Xander Berkley (Gregory) had the fewest, appearing in only five episodes.
Because of Eugene Porter's actions in season seven, actor Josh McDermitt received a large number of death threats and unpleasant messages through social medias. As a result of this, McDermitt deleted every single social media account in late April 2017, and has up until mid June not activated it again. McDermitt said in an interview, that he isn't sure whether or not he will return to social media, only that it depends on how the story on the show progresses.
Beth Greene (Emily Kinney) is a fan of Tom Waits. In a scene in season three, episode eleven, "I Ain't a Judas", she sings "Hold On" to the group in the prison. She also sings a portion of "I Don't Want to Grow Up" to baby Judith in season four, episode two, "Infected".
The trivia items below may give away important plot points.
In the show, Michonne hates The Governor (David Morrissey) based on a hunch, and he only loses an eye. However, in the graphic novels, he brutally rapes her for days, leading to the loss of his eye, arm, and testicle, when she gets her revenge.
The season six opener features a scene in which Rick (Andrew Lincoln) asks Morgan (Lennie James) who taught him to fight with a staff, and Morgan remains silent. In response, Rick says, "I ask, you answer. Common courtesy, isn't it?" This is a reference to the series premiere, where the roles were reversed, as Morgan is questioning Rick about his wound.
In the season two premiere, Rick is on a rooftop in Atlanta, talking to Morgan Jones on a walkie talkie. In the background, Grady Memorial Hospital (which is featured in season five) is clearly visible.
Dale had not originally been scheduled to die as early as he did in the show. However, after his close friend, Frank Darabont, was fired as showrunner, DeMunn asked to be killed off. Later, he had a change of heart, but his death had already been scripted and budgeted for, so his request to continue on the series was denied.
In the comics, during The Governor's prison attack, Judith is killed after Lori is shot, and falls on top of her. The writers used this to worry comic book fans when Judith's carrier was filled with blood in season four, episode eight.
The last line of season four on television is "They're screwing with the wrong people!" However, on disc, Rick says "f-cking" instead of "screwing". Andrew Lincoln only did one take of the censored version, because he liked the similarities to the comics.
The last five episodes of season five (Remember, Forget, Spend, Try, Conquer) are named based on a quote by Dale in season one: "I like what a father said to his son when he gives him a watch that had been handed down through generations... I give it to you not that you may REMEMBER time, but that you may FORGET it for a moment now and then and not SPEND all of your breath TRYing to CONQUER it."
The set used in the construction site scene, where Abe is collecting materials for Alexandria, is actually the prison set, after being stripped down. You can see this by looking at the building behind them. It has burn marks from the Governor's attack.
In the season five premiere, when the Terminites were slicing throats, the main cast members were not told about the prosthetic necks and fake blood that would ooze through the trough in front of them. This caused them to act as if they were surprised, and as if they'd never seen anything like it.
The coat that Rick wears in the last episodes of season four, and most of season five and six, belongs to "Claimer Lou", the man he strangled in the bathroom at the house, in which he, Carl, and Michonne were staying, after the prison.
A few seconds after the season five mid-season finale "coda" ended, AMC's facebook page mistakenly shared a picture of Daryl carrying Beth's corpse, with the caption "R.I.P. Beth". It was badly received by people who had not watched the episode yet in the West Coast, Europe, and South America.
At the beginning of season one, episode five, Edwin Jenner mentions in his live video recording, that it has been one hundred ninety-four days since "wildfire" (when the disease got out of control, but not yet global). This episode is on the fourth day after Rick wakes from his coma. If there is no mention or signs of a "disease" at the time of Rick's nearly fatal shooting (first episode), this suggests he could've been comatose for over six months.
The place where The Governor, Martinez, and Shumpert camp in the season four, episode six flashback, is the same place where The Governor and his soldiers wiped out the National Guard in season three, episode three.
On November 10, 2015, it was announced that Jeffrey Dean Morgan had been cast as the well known villain Negan. Negan was scheduled to make his first appearance in the season six finale, which was scheduled to air on April 3, 2016.
Baseball bats have been featured more so throughout season five, possible to foreshadow a death like Glenn's comic book death, though with a different character. Kirkman debunked any predictions about Glenn dying in this way during an "@midnight" segment called "Fake Spoilers". Ultimately, these predictions ended up coming true anyway, with Glenn's death exactly mirroring the graphic novel.
Beth's death, in the season five mid-season finale, caused an uproar on social media, with fans sending hate mail and death threats to Scott M. Gimple, along with boxes of plastic spoons being sent to AMC studios (a reference to the silver Washington, D.C. spoon Beth Found). A Change.org petition titled "Bring Beth Back" was also created, and had collected over one hundred thirty-five thousand signatures, and was even discussed on Good Morning America (1975).
In Breaking Bad (2008), Walt rents a red Dodge Challenger from a man named Glenn. Coincidentally, Glenn Rhee, from this show, drives an exact model in the season one episodes: "Guts" and "Tell It To The Frogs".
Many deaths on the show, and in the comic are similar, albeit with different characters. In the comic, it is Carl who shoots and kills Shane, and Rick who kills the walker Shane. On the show, Rick stabs Shane, and Carl shoots the undead Shane. Dale's fate is shared with Herschel and Bob. In the book, Dale loses a leg to a walker and The Hunters. In the comic book, it is Tyreese who is beheaded by the Governor, in the show, it's Herschel. On the show, Tyreese is bitten on the arm, and it is chopped off by Michonne, in the comic book, it is Morgan Jones.
Lauren Cohan and Jeffrey Dean Morgan cameo as husband and wife, Thomas and Martha Wayne in Batman v Superman: Dawn of Justice (2016). This is ironic, however, because Morgan's character, Negan, kills Cohan's character, Maggie's husband, Glenn in the comics, and the television series. Both also portrayed characters on Supernatural (2005), with Morgan notably playing Sam and Dean's father, John Winchester. Lauren Cohan played the antagonist Bela.
The church structure that plays a prominent role during the first half of season five, was not a real church. It was built from the ground up, and then aged to look appropriately worn and real. In the DVD extras, it is explained that they decided they had to build a new structure, instead of filming in a practical church location, because they knew from before the season started, that the brutal and bloody events in "Four Walls and a Roof" would have to be filmed there, and they were quite certain that no actual church would allow for those actions to be simulated on their grounds. By contrast, the town of Alexandria (which plays a similarly prominent role in the second half of season five) is not only a real community (Senoia, Georgia), but the development, in which the show is filmed, has a codicil in its charter, that its residents have to allow movies and television shows to be filmed there.
When Andrea shoots herself with Rick's revolver, you hear the empty brass casing hit the ground. But revolvers do not automatically eject the casing. However, this is a goof, and not a point of trivia.
All of the seven main characters died, as of the end of the fourth season. With the exception of Andrea; Dale, Merle, The Governor, Lori, Shane, and Hershel have all been brought down mercilessly by another character, whether it's before or after reanimation (Andrea committed suicide).
Lori has sexual relations with both Shane and Rick within a 24-hour period, and it is implied that it was her first time to be with Shane (she removed her necklace with Rick's wedding ring). This could easily make Shane or Rick, Judith's biological father. Towards the end of season one, in the CDC, Shane says to Lori, "You know, you and I carried on quite a bit", implying what we saw wasn't the only time they had been together.
When Bob, Tyreese, Daryl, and Michonne hear the Terminus broadcast message from the radio, it was eight days before Bob would make his way there, and nine days before Daryl and Michonne would. Tyreese does not enter Terminus.
Scott Wilson, who plays Hershel Greene, appeared in the television movie The Jack Bull (1999) as a character called "Governor". Ironically, he gets killed by The Governor (David Morrissey) in this show. Wilson also plays a Governor in Young Guns II (1990), the role of the real-life Governor Lew Wallace, who promised to pardon Billy the Kid.
With Beth dying in the midpoint of season five, and Tyreese dying in the first episode of the season, this makes two deaths back to back. This also happened on season three, episodes fifteen (Merle) and sixteen (Andrea), as well as season two episodes eleven (Dale) and twelve (Shane). Lori and T-dog also die back to back. However, in the same episode, season three, episode four.
At the end of the pilot episode, when Rick is in Atlanta, the tank, in which he locks himself, to get away from the walkers, is a British Chieftain Mark 11 tank, and not an American M1 Abrams tank, as could be assumed.
