Mädchen Amick appears in the first season of "Riverdale" as Alice Cooper, the sharp-tongued and image-conscious editor of the Riverdale Register. As Betty Cooper’s demanding mother, Alice is deeply invested in maintaining the town’s social hierarchy and her family’s public reputation. Amick plays Alice as commanding and intimidating, often clashing with her daughter while projecting an air of strict control within the Cooper household. Her character quickly emerges as one of the most formidable adult figures in Riverdale.
Throughout the season, Alice becomes increasingly involved in the fallout from Jason Blossom’s murder, frequently inserting herself into town controversies and using her position at the newspaper to shape public perception. While she initially appears rigid and judgmental, the story gradually reveals layers of insecurity, past relationships, and complicated ties between Riverdale’s parents that help explain her behavior.
Amick was already widely recognized for her role as Shelly Johnson on "Twin Peaks," where she portrayed the troubled waitress entangled in the town’s dark secrets. The role helped establish her as a memorable presence in television drama and remains one of her most iconic performances.
Over the years, she built a steady career across television, with major roles including Wendy Beauchamp on "Witches of East End." She has also appeared in series such as "ER," "Gilmore Girls," "Californication," and "Damages." With decades of television experience, Amick brings authority and depth to "Riverdale," grounding Alice Cooper as a powerful and complicated presence among the town’s adults.
