Mirror, Mirror is a 1990 American supernatural horror film directed by Marina Sargenti, based on a screenplay by Annette Cascone and Gina Cascone. It stars Karen Black, Rainbow Harvest, Yvonne De Carlo and William Sanderson. The film follows a teenage outcast who finds herself drawn to an antique mirror left in the house she and her mother have moved into. A soundtrack was released in 1990 through Orphan Records. Three sequels followed in 1994, 1995 and 2000.

In 1950s Iowa, Mary Weatherford sacrifices her sister Elizabeth in front of a large mirror, stabbing her to death on a bed. Decades later, Megan Gordon, a shy teenage goth, moves to Los Angeles, California with her recently widowed mother Susan. In her new bedroom, Megan finds the large mirror in the corner left behind by the previous owners. Emelin, the auctioneer in charge of the house clearance, finds a cache of journals that describe the mirror's apparent possession by a demonic force able to grant wishes.

At her new school, Megan is taunted mercilessly by her peers, apart from the friendly Nikki as well as handsome, athletic Ron. Charleen, a bully running for class president against Nikki, quickly targets Megan. Meanwhile, as Megan becomes drawn to the mirror in her room, she's plagued by bizarre incidents at home; her mother's dog mysteriously dies, she's visited by a gruesome apparition of her dead father, and the mirror begins inexplicably dripping blood. Megan becomes convinced that the mirror is responsible for a series of misfortunes involving those around her, including Charleen experiencing a massive nosebleed in the cafeteria, and her teacher, Mr. Anderson, having a severe asthma attack during class.

Realizing the mirror's powers, Megan begins harnessing them herself, using them to manipulate Jeff, Charleen's love interest, into developing a crush on her instead. When Jeff stops a sexual encounter, the demon in the mirror brutally murders him before making his body disappear. The next day, Emelin attempts to retrieve the mirror from the house while Megan and Susan are gone, but her hands are mysteriously impaled, leading her to flee. When Nikki loses the student council race to Charleen, Megan harnesses the mirror's powers to scald Charleen to death in the girls' locker room showers, before killing Charleen's friend Kim in a bathroom.

Nikki becomes discomforted by Megan's change in personality, and is disturbed when Megan suggests she "helped" her usurp the class presidency. Nikki meets with Mrs. Perfili, the local real estate agent, and Emelin to inquire about the history of Megan's house and the mirror. Emelin reveals the content of the journals to Nikki, and explains that Mary Weatherford sacrificed her sister in front of the mirror decades ago hoping to appease it. After Nikki leaves, Emelin is impaled to death with a shard of glass at her antiques store.

That night, Ron is attacked by a doppelgänger of Nikki in his house and brutally murdered. After finding Ron's body, Nikki receives a phone call from Megan asking her to come to her house. Meanwhile, Susan has her hand mangled in the garbage disposal in the kitchen and bleeds to death, leading Megan to turn against the mirror. Nikki arrives armed with a dagger and attempts to shatter the mirror, but it is resistant. She and Megan attempt to flee as a torrent of wind fills the house, but are unable to escape. Megan sacrifices herself to the mirror, thus ending its reign of terror. Nikki invokes the mirror, begging it to restore things back to how they were before. She awakens in the room on the bed, dagger in hand, with Megan's corpse beneath her, in the same position as Mary Weatherford, having been subjected to an apparent time loop. The demon shows itself in the mirror before retreating, and Nikki fearfully covers it with a sheet.
