A witch’s 16th birthday is very special.

Not that we weren’t already, but we’re now 100% all-in on Netflix’s comic book adaptation “Chilling Adventures of Sabrina,“ which debuts its first footage in a teaser today.

The teaser trailer is loaded with creepy imagery, doubling down on the series’ promise to be *so much* darker than Sabrina’s first TV series. This looks like pure Halloween glory.

“Chilling Adventures” is headed our way on October 26.

The series is set to be an hour-long drama that will reimagine the story of Sabrina the Teenage Witch as a dark coming-of-age tale that traffics in horror, the occult and witchcraft.

“This adaptation finds Sabrina wrestling to reconcile her dual nature — half-witch, half-mortal — while standing against the evil forces that threaten her, her family and the daylight world humans inhabit.”

Kiernan Shipka (“Mad Men”) was cast as Sabrina Spellman, a new take on the character originally played by Melissa Joan Hart. Jaz Sinclair (Paper Towns) co-stars. Sinclair will play the role of Rosalind. Brash, empowered, and outspoken, Rosalind Walker is the daughter of Greendale’s minister and Sabrina’s best friend at Baxter High.

Ross Lynch (My Friend Dahmer) will play Harvey Kinkle, Sabrina’s boyfriend. The prince charming of this dark fairy tale, Harvey is the son of a coal miner, a dreamboat and a dreamer, completely unaware of the dark forces conspiring to keep him and Sabrina apart.

Michelle Gomez (“Doctor Who”) will play Mary Wardell, Sabrina’s (Shipka) favorite teacher and mentor at Baxter High. When she is possessed by the Devil’s handmaiden, Madam Satan, Ms. Wardell turns into a sultry, cunning manipulator who is always trying to lure Sabrina down the Path of Night.

Chance Perdomo is Ambrose Spellman. The character is Sabrina’s warlock cousin from England. Placed under house-arrest by the Witches Council, Ambrose is forbidden from leaving the funeral home where he lives with the Spellman women. Witty, puckish and pan-sexual, he is one of Sabrina’s partners in crime, always up for mischief.

Lucy Davis (Wonder Woman) has been cast as Hilda Spellman, one of Sabrina’s two witch aunts. More nurturing than Zelda, Hilda’s motherly nature and warm sense of humor belie a wicked, ghoulish streak. She is as adept at brewing spite jars against her family’s enemies as she is at concocting love potions for the students at Baxter High.

Miranda Otto (Annabelle: Creation) is Zelda Spellman, Sabrina’s other aunt. Proud and devout, Zelda believes there is no greater honor than serving the Dark Lord as a member of the Church of Night. She is the family’s disciplinarian, fiercely protective of Sabrina, and very much Cain to aunt Hilda’s Abel.

Richard Coyle (The Collection) is Father Blackwood, High Priest of the Church of Night and Dean of the Academy of the Unseen Arts. Ruthless and ambitious, Blackwood hides a terrifying dark agenda that will put him in direct conflict with Sabrina and other members of the coven.

Tati Gabrielle (“The 100”) who will play Prudence, a student at the Academy of Unseen Arts and the de facto leader of a trio of witches known as the Weird Sisters. Beautiful and cunning, Prudence nurses a deep, personal, and possibly life-threatening grudge against Sabrina.

Roberto Aguirre-Sacasa executive produces and writes. Lee Toland Krieger will executive produce and direct. Other executive producers include Greg Berlanti, Sarah Schechter (Berlanti Productions) and Jon Goldwater (Archie Comics).
