The wizarding world is returning — and this time, it’s coming to your television for a decade-long adventure. HBO’s highly anticipated Harry Potter series has been steadily confirming its cast, and the lineup is nothing short of magical. From fresh-faced child actors to Hollywood heavyweights, here’s every confirmed actor and the role they’ll play.
Harry Potter Main Trio: New Faces, Iconic Roles
After reviewing over 32,000 auditions, HBO finally revealed the three young stars who’ll carry the franchise forward.
