The highly-anticipated Netflix reboot of the '90s series "Sabrina," "The Chilling Adventures of Sabrina," is arriving Oct. 25. Netflix made it clear with the dark and haunting official poster that any memory of Melissa Joan Hart's lighthearted antics should be firmly left behind, and now the show has revealed the biggest glimpse yet at what we can expect from the new and improved teenage witch.Delivering the latest glimpse into the world of dark magic, Netflix has dropped a whole selection of stills taken directly from upcoming episodes of the thriller series, including a great look at characters like Aunt Hilda, Aunt Zelda and Harvey Kinkle 2.0. Among them is the first glimpse of actress Michelle Gomez, who plays Sabrina’s evil teacher, Mary Wardell. She’s otherwise known as Madame Satan, which hints at her teaching style.Madame Satan is apparently a servant of the Dark Lord, who’s possessed Sabrina’s favorite teacher in order to ensure she’s led down the Path of Night. Next up is the first glimpse of Sabrina’s iconic aunts, Hilda and Zelda. Zelda, described as a devout follower of the Church of Night, determined for her niece to follow in her family’s footsteps, is played by "Lord of the Rings" actress Miranda Otto. And of course, where there’s an Aunt Zelda, there’s an Aunt Hilda. Played by Lucy Davis (who you might recognize from the British version of "The Office"), Hilda is definitely a little kinder than Aunt Zelda but still just as evil. Then, there’s many original fans' first '90s love, Harvey Kinkle — this time brought to life by Ross Lynch. In the 2018 remake, he’s the son of a coal miner who is totally oblivious to Sabrina’s secret magic heritage.Check out the rest of the photos for an insight into characters set to appear in "The Chilling Adventures of Sabrina" with whom you may not be quite so familiar.
