Many mysteries remain about the fate of Ophelia Frump, but after years of dark speculation, she now has a face: French actor Eva Green (Miss Peregrine’s Home For Peculiar Children, Dark Shadows) joins the upcoming third season of Wednesday as the allegedly missing sister of Morticia Addams (Catherine Zeta-Jones) — or, as Wednesday (Jenna Ortega) and Pugsley (Isaac Ordonez) have always referred to her, Aunt Ophelia. Her casting also marks a reunion with longtime collaborator director Tim Burton.

Creators, showrunners, and writers Al Gough and Miles Millar tell Tudum exclusively, “Eva Green has always brought an exhilarating, singular presence to the screen — elegant, haunting, and beautifully unpredictable. Those qualities make her the perfect choice for Aunt Ophelia. We’re excited to see how she transforms the role and expands Wednesday’s world.”

Green tells Tudum, “I’m thrilled to join the woefully twisted world of Wednesday as Aunt Ophelia. This show is such a deliciously dark and witty world, I can’t wait to bring my own touch of cuckoo-ness to the Addams family.”
