100 free Harry Potter and the Prisoner of Azkaban trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Prisoner of Azkaban is the Harry Potter book with no Voldemort, a werewolf teacher, a rat who is really a man and a time-travel ending, and the film that turned the series dark under Alfonso Cuaron. This Harry Potter Prisoner of Azkaban trivia quiz covers both: Aunt Marge inflating, the Knight Bus, the Dementors on the Hogwarts Express, Lupin's Patronus lessons, Buckbeak and Draco, the Marauder's Map, the Three Broomsticks eavesdrop, the Shrieking Shack reveal, Hermione's Time-Turner and the Firebolt at the end. It also covers the making of the story: how quickly the book sold in July 1999, the awards it won, why Michael Gambon replaced Richard Harris, why Ian McKellen said no, the essays Cuaron made the young cast write, the Glen Coe and Glenfinnan locations, John Williams's Double Trouble, the Oscar nominations and why the highest-rated Potter film is also the lowest-grossing. Forty-eight questions run from easy for anyone who has read book three to expert for fans who know their proof editions. Every answer is checked against documented sources, so it works for a Potter night, a book club or a family movie round.
