Helen Mirren is oddly absent from the Harry Potter film franchise that proved close to a full-employment act for Britain’s acting greats. But she’s found her own path into its magical world.

Dame Helen, as the Oscar, Emmy and Tony-winning actor is properly addressed, makes her debut as a quiz host with “Harry Potter: Hogwarts Tournament of Houses.” The weekly, four-part series begins 8 p.m. EST Sunday on TBS and Cartoon Network.

In episode one, contestants representing the Gryffindor and Hufflepuff houses field trivia questions about J.K. Rowling’s novels-turned-films in a bid to claim a championship trophy and prizes.

Mirren left the cramming to the players and is unworried about being a novice game show emcee.

“I can certainly play a strict host,” she said, drolly, in an interview with the Associated Press.

Mirren’s willingness to take on something different shouldn’t raise eyebrows. She’s celebrated for her regal roles — including “The Queen,” “Elizabeth I” and “Catherine the Great” — but also counts the Fast the Furious movie franchise among her varied credits.

Her return to a comic book-based project is upcoming: She plays a mythological goddess in “Shazam! Fury of the Gods.” Mirren’s baptism in the genre came with the film “Red” and its sequel.

Mirren’s admiration for the Harry Potter series rings true.

“I’m always up for a bit of an adventure. Also, of course, it’s a wonderful subject and at a great moment, the 20th anniversary (of “The Sorcerer’s Stone,” the first Potter film),” she said. “And the very fact I was never in any Harry Potter movies — much to my chagrin, I might add. It was a great way to to be able to participate in the whole extraordinary phenomena that is Harry Potter.”
