Cartoon Network, TBS and then HBO Max will celebrate the 20th anniversary of the Harry Potter film franchise with the previously announced four-part competition series Harry Potter: Hogwarts Tournament of Houses. “I knew someday I’d get a Harry Potter role, and I’m so pleased to take part in the 20-year film celebration,” Mirren said. “The films inspired such enchantment and wonder for so many of us, and it will be such a treat to reignite that magic for the countless fans who continue to revel in this spellbinding world.”
