Wands at the ready -- and prepare to test your Hogwarts knowledge.
To celebrate the 20th anniversary of "Harry Potter & The Sorcerer's Stone" hitting theaters, HBO Max is giving fans a special four-night quiz show series and a retrospective special later this year, according to Variety.
A trailer for "Harry Potter: Hogwarts Tournament of Houses" just dropped and features die-hard fans representing their respective houses -- Gryffindor, Slytherin, Hufflepuff, and Ravenclaw -- and competing against one another in answering questions faster than Hermione Granger. Only one will come out victorious and take home the ultimate championship trophy.
Helen Mirren is set to host, but you can also expect guest-appearances from some of the wizarding world's finest, including Tom Felton (Draco Malfoy) and Matthew Lewis (Neville Longbottom). Superfans Jay Leno and Pete Davidson will also be involved.
The quiz show will air on HBO Max, Cartoon Network and TBS over four nights starting Nov. 28 at 8 p.m. ET/PT with "Gryffindor vs. Hufflepuff" first. Ravenclaw and Slytherin will face-off next before the two winning houses move on to the wildcard episode and then the grand finale.
Fans will be able to join in on the fun from home for a digital quiz on WizardingWorld.com starting Nov. 26 through Dec. 10.
A twenty-year retrospective "Harry Potter" special will also air across the three networks once the game show series concludes.
“To celebrate the dedicated fans old and new who have passionately kept the Wizarding World magic alive in so many forms for decades, these exciting specials will celebrate their ‘Harry Potter’ fandom in a must-see multiplatform TV event,” said Tom Ascheim, president of Warner Bros. Global Kids, Young Adults and Classics, in a statement.
“All Potter fans can gear up for this ultimate one-of-a-kind celebration by embracing their inner Hermione Granger and studying their Wizarding World knowledge. For fans who have always wanted to discover what it might be like to take the O.W.L. exams, this is as close as they are going to get!”
While there had been reports that HBO Max was working on a live-action "Harry Potter" TV series, HBO chief content officer Casey Bloys recently denied those rumors.
"There are no deals in place. There are no writers. There's nothing," Bloys told Entertainment Weekly in February. "So I can't add anything to what everybody's already speculating about."
"Harry Potter and the Sorcerer's Stone" first premiered in the US on November 16, 2001.
