Was originally meant to be the fourth movie, but due to so much material being written, the makers decided to turn it into a television series instead. If the first season was a movie, it would've been around five hours long.

The yellow Oldsmobile Delta 88 that Ash drives is the same make, model, and color used in most of the movies directed by Sam Raimi. The original car belongs to Creator and Writer Sam Raimi, and was bought new by his father.

It was given approval of a second season three days before it premiered on Starz on October 31, 2015.

Early in the first episode, Ash is seen performing a "powerslide", which is a stunt that requires the driver to steer the car into a tight turn at high speeds, and apply the parking brake, which causes the back tires to lose traction with the road and slide into the turn. Bruce Campbell has revealed that he was taught to perform this move by William Shatner, who was known to perform the stunt regularly on T.J. Hooker (1982).

Sam Raimi originally intended to follow Army of Darkness (1992) with a fourth Evil Dead movie; the plan for which was to follow the theatrical and director's cut endings of the film with a film that followed two different timelines simultaneously. The concept was eventually abandoned, due to its complex nature.

The third film of the franchise, Army of Darkness (1992), had to be largely ignored in the first season because Starz couldn't get the rights from Universal Pictures. The creators confirmed that Ash's trip to Medieval times did occur, but it just couldn't be referenced for legal reasons. This is a familiar situation for creator/director Sam Raimi, as the studio that had distributed The Evil Dead (1981) denied him permission to re-use some of its footage in Evil Dead II (1987). However, at San Diego Comic-Con 2016, producer Rob Tapert announced that in the wake of the show's popularity, Universal had given them permission to use elements from Army of Darkness for season two.

Picks up thirty years after the events of The Evil Dead trilogy. For the first season, Universal Pictures/MGM did not allow Starz to use footage or elements from Army of Darkness (1992). For the second season, Universal/MGM gave Starz permission to use elements from Army of Darkness (1992).

Joseph LoDuca, the music composer for several Sam Raimi films including The Evil Dead (1981), Evil Dead II (1987), and Army of Darkness (1992), returned to score this show.

Ellen Sandweiss reprised her role as Deadite Cheryl and ad-libbed her line, "I'm gonna make like a tree, and f**k you!", referencing her infamous "Tree Rape" scene from The Evil Dead (1981). Original Director Sam Raimi expressed his regret for the scene multiple times, while Sandweiss on the other hand defended it, stating that it was one of the scariest scenes in any horror film.

The fact that Ruby's Kandarian Dagger can sear the flesh of the possessed wasn't created for this show. It is seen doing this in The Evil Dead (1981) when Scotty used it to stab the possessed Shelly in the back, and she uncharacteristically reacts in extreme pain for a Deadite. Blood and smoke are then seen pouring out of the mouth of the ornamental skull on the blade's handle.

This show marks the first appearance of Bruce Campbell as Ash since the Evil Dead: Regeneration (2005) video game, not including his cameo at the end of Evil Dead (2013).

The songs that appear in the series' soundtrack are all from the 1970s and 1980s and were picked by Sam Raimi and Rob Tapert because they believed they would be songs that Ash listened to back before his first demonic encounter in the cabin and symbolized his lack of growth since that night, with Raimi stating "the music should reflect the last time he was engaged in society, and living."

Even though Universal Pictures barred Starz from referencing Army of Darkness (1992) in the first season, the series seemed to try to get around this by giving Ash a robotic hand and an evil clone, both of which appeared in the film. After killing said clone, Ash even implied it's not his first time killing and dismembering an evil clone of himself. However, since the show has caused a rise for demand in The Evil Dead trilogy home videos, including Army of Darkness (1992), Universal granted Lionsgate (now parent company of Starz) permission to reference and use footage from the film.

Ellen Sandweiss (Cheryl) is the only other cast member from The Evil Dead (1981) to appear and reprise her role.

Executive Producer Rob Tapert is married to Lucy Lawless (Ruby Knowby).

To give Pablo and Kelly their own iconic look to stand up to Ash's classic blue shirt and brown pants, the Wardrobe Department created an individual tone to their costumes. Pablo always wears clothing with the color green and graphic t-shirts, and Kelly always wears purple-colored apparel along with distinctive rings she wears that spell out different words in each episode. They also created multiple versions of Ash's wardrobe for diverse reasons, including blood splatter, tears, and stunt work. They even had a collection of shirts that was a lighter tone of blue for scenes with darker lighting.

Mimi Rogers threw out her back a couple days before shooting her cameo as Kelly's mother. Nevertheless, she insisted on performing as many of the stunts she could physically do, including fight scenes, falls, and crawling on walls.

In the season one finale, Ash returned to the basement of the cabin where it all began. When he is entering the next room, his flashlight reveals a brief glimpse of Freddy Krueger's glove, which can be seen as he goes after Ruby and Pablo; right before he wrongly calls Pablo "Pedro". This leaves people to believe, much like the comic series "Freddy vs. Jason vs. Ash", this series exists in the same universe as A Nightmare on Elm Street (1984) and Friday the 13th (1980). However, this is unlikely, since those franchises belong to New Line Cinema and Paramount Pictures, whereas this series is owned by Lionsgate.

Bruce Campbell and Lucy Lawless appeared on Xena: Warrior Princess (1995) and Burn Notice (2007).

The Kenward asylum, to which Ash is taken by Baal, was filmed at a decommissioned mental institution. Parts of the grounds there are now home to New Zealand's major "scaremusement" park, Spookers.

A make-up test photo of Samara Weaving was used as propaganda by a Twitter account called "Conservative Nation", claiming her to be a bludgeoned Donald Trump supporter who was beaten by numerous liberals. Not only was this false, but she wasn't an American citizen, nor was the photo taken in the United States. It wasn't until Bruce Campbell proved it to be false that they deleted the post. It wasn't until they received numerous angry messages from both liberals and conservatives, that they deleted the account entirely.

It was given approval on November 11, 2014 for ten episodes on the Starz network in 2015.

Sian Davis (Ash's elderly neighbor Vivian) appeared on an episode of Hercules: The Legendary Journeys (1995), which was produced by Sam Raimi and Rob Tapert and co-starred Bruce Campbell. She was also the voodoo doctor seen in the opening scene of Evil Dead (2013).

It has been twenty-three years since Bruce Campbell has starred in the live-action role of Ash Williams, if you don't count his cameo appearance in Evil Dead (2013).

Starz could not get the rights to Army of Darkness (1992) for the first season, which is why the events of this movie weren't mentioned or otherwise referenced, nor any footage shown until season 2. This helps to explain why Ash no longer has his iron hand, and why the store he works at is called Value Stop instead of S-Mart.

In the first season, Ash's severed hand was originally supposed to be contained by Ruby in a glass cylinder full of clear liquid. Some scenes were shot with it, but it was decided that the curved glass of the cylinder warped the look of the hand to appear three times bigger than its actual size, and distorted its appearance. So the cylinder was abandoned and all scenes with it were re-shot without it. This explains why some scenes involving the hand are CGI, and many others are either puppets or an actual hand that was digitally enhanced.

This show continues the tradition set forth by The Evil Dead trilogy, in that each episode begins right where the previous episode left off.

Sid Haig auditioned for the role of Brujo.

Lucy Lawless, Ted Raimi, and Joel Tobeck and Bruce Campbell appeared on Hercules: The Legendary Journeys (1995) and Xena: Warrior Princess (1995).

Starz canceled the series after three seasons due to low ratings.

In season two there is a picture of the late night movie host "The Ghoul" just at the corner of Ash's bed in his childhood home. Also, there are numerous beer posters with the name "Shemp", but in the stylized look of Stroh's beer.

Bruce Campbell announced that the cancellation of Ash vs Evil Dead marked the end of him portraying the character Ash Williams for good.

In the last three episodes of season one, several elements of the cabin set contradict their appearance in Evil Dead II (1987). For instance, the stairs to the basement were originally torn down during Ash's battle with Henrietta in the film, but are still standing on this show. Some latticework constructed of sticks on the side of the cabin that was torn down by the possessed Ash while attacking Annie in the film are still standing on this show. The front door was torn off by the evil force during Ash's fight with the demon, but is back in its place on this show. Several shelves hanging in the kitchen that fell off during the trees attack on the cabin in the film are back on the wall, as well as some boards covering broken windows that fell off, but are back in place. Another example is the cross over Linda's grave is still standing, even though we saw it fall when she originally rose from the dead in the film.

By directing The Evil Dead (1981), Evil Dead II (1987) and Army of Darkness (1992), as well as the pilot episode of this series, Ash vs Evil Dead: El Jefe (2015), Sam Raimi has been involved as a director in every installment of the original Evil Dead series. He produced but did not direct Evil Dead (2013), which was rumored to be set in the same universe and would even lead to a cross-over with the rest of the series, but this never materialized.

Every episode starts with a scene where a blood splatter transitions seamlessly into the title card.

Milo Cawthorn (Delmont) who appeared in Deathgasm (2015) was offered a short role because of Deathgasm (2015) and The Evil Dead (1981) movie similarities. Both are about teenagers who unknowingly summon demons that were caused from certain passages being read from an object that were both written in blood, both have survivors that need to find a way to reverse the curse by using the object that was used to accidentally release the demons in the first place, both movies involve the usage of chainsaws, and both involve the deaths of friends and family getting killed.
