The event, officially titled “Harry Potter: Hogwarts Tournament of Houses,” will put superfans of the beloved book and film series to the test as they use their “Harry Potter” knowledge to compete for the coveted House Cup. The special will feature hundreds of “Harry Potter” trivia questions and include a few special guest appearances. Although a date for the event has yet to be announced, it will be simulcast on Cartoon Network’s ACME Night and TBS and will then be available to stream on HBO Max.
“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 in a statement. “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.”
The special is set to film this month and will premiere later this year. “Harry Potter and the Sorcerer’s Stone” debuted in theaters on Nov. 14, 2001.
“We’re creating an arena for the leagues of ‘Harry Potter’ film fans to flex their knowledge of the Wizarding World, and there’s no one better than Dame Helen Mirren to add some British grandeur to this event that will debut across our WarnerMedia brands and platforms,” added Tom Ascheim, president of Warner Bros. global kids, young adults and classics.
“Harry Potter: Hogwarts Tournament of Houses” is being produced by Warner Bros. Unscripted Television, in association with Warner Horizon and Robin Ashbrook and Yasmin Shackleton of theoldschool.
