The HBO Harry Potter show is still filming, and it is set to continue for the coming months. Season 1 adapts Philosopher's Stone, will introduce several fan-favorite characters like Hagrid, Dumbledore, Ron, and Hermione. But considering all seven books are published, fans are expecting the HBO adaptation to stick to the books more than the movies.People celebrate the eight movies, but one common complaint fans have is that they cut out important plotlines. One of the plotlines that the movies cut out is from the big-screen adaptation of Goblet of Fire. The fourth book sets up the Weasleys' Wizard Wheezes, which debuted in the sixth book, Half-Blood Prince.While the Weasley Twins' joke shop appears in the sixth movie, it does not reveal how they managed to open the shop in the first place. However, the Goblet of Fire book reveals who funded the joke shop in the first place.Harry's Triwizard Tournament winnings funded the shop in the Harry Potter and the Goblet of Fire book:Earlier chapters of the fourth book mention that the twins are experimenting on something inside their room in The Burrow. We later learn that the twins are working on products for a joke shop, much to the chagrin of Mrs. Weasley. They are at odds with their mother throughout the entire book.Things only get complicated as they place a bet during the Quidditch World Cup with Ludo Bagman, a character the fourth movie cut out. They win the bet, but Bagman avoids paying them. The book ends with both Harry Potter and Cedric Diggory winning, but the Triwizard Cup is revealed to be a portkey, a trap for Harry. They are soon transported to a mysterious graveyard, where Cedric is killed.Thus, Harry gets all the Triwizard Winnings, and he learns about Ludo Bagman's refusal to pay the twins. As the twins decide to give up on their dream to open a joke shop, Harry gives them his winnings under one condition: that they buy Ron a new uniform. Since Ludo Bagman is cut out of the Goblet of Fire movie, it also left out the part where Harry hands them his Triwizard Winnings.The HBO series can hint at the twins' future right from the first season: View this post on Instagram Instagram PostTwin brothers, Tristan and Gabriel Harland, are playing Fred and George Weasley in the HBO series. The first season features Cornelius Fudge and Lucius Malfoy despite their first appearance in the next book, Chamber of Secrets. Therefore, the writers could set up the seeds for the Weasleys' Wizard Wheezes right in the first season by including scenes of the twins coming up with ideas for various items.Adding these scenes would not change much from the original storyline; it would just flesh out the characters, giving the show a separate identity from the movies, which were from the perspective of the main trio most of the time."Harry Potter has never even heard of Hogwarts when the letters start dropping on the doormat at number four, Privet Drive. Addressed in green ink on yellowish parchment with a purple seal, they are swiftly confiscated by his grisly aunt and uncle. Then, on Harry’s eleventh birthday, a great beetle-eyed giant of a man called Rubeus Hagrid bursts in with some astonishing news: Harry Potter is a wizard, and he has a place at Hogwarts School of Witchcraft and Wizardry. An incredible adventure is about to begin!"The HBO Harry Potter series does not have an official release date, except for a 2027 release window. But all eight movies are streaming on HBO Max, and Audible is also currently releasing audio editions of the books, of which two books are already available.
