The Weird Sisters are a trio of Witches in the Shakespeare play Macbeth. The spell Sabrina uses to summon them is taken directly from actual lines spoken by the witches in Macbeth (Act 1, scene 3)

Over 150 paintings were contributed by Clive Barker (mastermind behind Hellraiser and Candyman) to use for the show.

Aunt Zelda appears to be fluent in at least a dozen languages, including French, Italian, Russian, Japanese, Spanish and German, as shown by the newspaper she is reading at the kitchen table on each episode.

This show takes place in the same universe as the CW series "Riverdale," which is based on the Archie comics and featured Sabrina as a character, who later received her own dark comic series.

The opening scene at the Paramount Theatre was filmed at the same Paramount Theatre in Stephen Kings 1990s TV movie IT.

The names "Hathorne" and "Putnam" are taken from Arthur Miller's "The Crucible" which takes place during the witch trials in Salem.

After it had originally been set to air on The CW, Netflix acquired the rights to produce the series in December 2017.

Dr. Sapperstein, who Mrs.Wardwell mentions in the car in episode 1 is the name of the satanic doctor in Rosemary's Baby (1968).

In this series, Salem doesn't talk or get as much screen time as he did in Sabrina - total verhext! (1996). One of the reasons behind this, besides the show pursuing a much darker tone, is that Kiernan Shipka is actually allergic to cats. At some point, showrunner Roberto Aguirre-Sacasa even considered turning Salem into a dog.

Kiernan Shipka was in her teens when the series premiered on Netflix, making her the first real-teen to play the teenage Sabrina Spellman in live-action TV series but the second overall. Melissa Joan Hart was entirely in her twenties when she starred on Sabrina - total verhext (1996) show, but was still only 19 when the non-canonical Sabrina - total verhext! (1996) aired earlier in the year.

Like Riverdale, the year in which the show takes place is intentionally never mentioned, so that the show can be simultaneously modern and retro. This is why elements of the town, schools, and much of the clothing in Greendale, is more reminiscent of the 1960s, when the source material is set, but there are also modern references, as well as cellphones and computers.

Kiernan Shipka had long brown hair when she did her first screen test for Sabrina. She was asked to come back and do another screen test with short blonde hair. After she changed her hair, she was offered the part. Ross Lynch was asked to dye his hair brown, since the producers felt that he looked too similar to Kiernan Shipka with blonde hair.

While cited as being based on characters from The Crucible, both the Putnam and Hawthorne families were actual Puritan families in Salem, MA. John Hathorne(later changed to Hawthorne) was the "Chief Examiner" during the Salem Witch Trials, and the Putnam family had multiple accusers in the Salem witch trials.

Gives homage to both Suspiria & A Nightmare on Elm Street. The living room has the same color glass ceiling seen in Suspiria(which is also about a coven of witches) and the scene with Harvey(Ross Lynch)falling asleep with headphones on and a crop top is homage to Johnny Depp's character in Elm Street.

The character of Father Faustus Blackwood - the right hand man of the Dark Lord (Devil) - is named from the German folklore character, Faust, who sold his soul to the Devil for infinite knowledge.

Takes place in the same universe as "Riverdale" which airs on the CW. "Supernatural" also airs on the CW and clearly shared actors with "The Chilling Adventures of Sabrina" if you look closely you can even spot the iconic 1967 Chevy Impala in the background of some shots.

The store and owner Cerberus on the show is a reference to the three headed dog from hell.

Kiernan Shipka (Sabrina) and Miranda Otto (Aunt Zelda) will co-star together in The Silence (2019).

Stolas, Wardwell's familiar, is neither a crow nor a raven but a hybrid of two birds, combining the size and proportions of a raven, yet retaining the beak shape of a crow. The visual effects crew refers to Stolas as being a "craven".

Lucy Davis (Aunt Hilda) previously played a witch when she starred in the children's TV show Belfry Witches (1999) as the mischievous Old Noshie.

In Sabrina's bedroom there is a poster of the movie Haxan (1922). It's a Swedish/Danish documentary style film on witchcraft through the ages.

Richard Coyle starred in British sitcom Coupling (2000) with Jack Davenport, husband of Chilling Adventures of Sabrina (2018) co-star Michelle Gomez.

When they're walking through the Apple orchard in episode 1, it's supposed to be near Halloween but the trees have spring flowers & fresh buds on them.

Michelle Gomez has appeared in two previous science fiction and fantasy programmes prior to this. Previously she was in Gotham and had a recurring role in Doctor Who has Missy the first ever female Master

Michelle Gomez (Madam Satan) and Richard Coyle (Faustus Blackwood) previously starred together in The Collection (2016).

Both Tati Gabrielle (Prudence) and Alessandro Juliani (Dr. Cee) have had recurring roles on The CW show The 100, as Gaia and Sinclair respectively, although they never shared a scene, Juliani's character was killed before Gabrielle's made her debut

Similarity in Father Faustus Blackwood played by Richard Coyle, being a warlock in this series and in Guy Ritchie's 2009 Sherlock Holmes starring Robert Downey Jr , the character Lord Henry Blackwood played by Mark Strong practiced Dark Magic or rather impersonated it.

When Sabrina (Kiernan Shipka) is reading her fathers diary, you can read the name Valac the defiler the profane the marquis of snakes. Which is the main character of the movie The Conjuring 2

Pays homage to John Carpenter's The Fog. Each opens with the narrator telling us there is time enough for one more story before midnight. The Witches are shrouded in fog as they attack the town. The 13 Witches were betrayed, with betrayal leading to their deaths, as were the Lepers at Spivey Point in The Fog. In both, there are characters with ancestral ties to those who were betrayed. In both, the antagonists seek revenge against the town that betrayed them.

In episode 9 when Roz is asking Sabrina if Tommy has come back alive, she mentions that "Mr. Baterman was delivering a UPS package...". This could be a reference to Timmy Baterman from Pet Sematary, who was also killed & resurrected.

The Doc Phibes mentioned after Tommy's resurrection is probably paying homage to the Vincent Price character played in "The Abominable Dr. Phibes" & "Dr. Phibes Rises Again"
