1. Ludo Bagman
In ‘Harry Potter and the Goblet of Fire’, Bagman plays a key role in both organizing and announcing the Quidditch World Cup and the Triwizard Tournament. However, in the film adaptation, it is Cornelius Fudge who announces the Quidditch World Cup, and Dumbledore instead instructs the Triwizard champion before each act.
2. Charlie Weasley
It was already bad enough that Bill Weasley played a much smaller role in the movies than in the books. Also, Charlie didn’t show up at all. It would have been great if he was given some space in ‘Harry Potter and the Goblet of Fire’ during some scenes for the first task of the Triwizard tournament.
3. Peeves
Although there are many ghosts in the Hogwarts castle, Peeves the Poltergeist is the most important. Mischievous ghosts can always be considered a cause of trouble for students and teachers alike. Even though he has no essential role in the plot, it’s strange to see Hogwarts on screen without his presence. In the books, he spreads rumors about Harry being Slytherin’s heir, reveals that Sirius Black has infiltrated the castle, and joins Fred and George Weasley to terrorize Dolores Umbridge.
4. Frank and Alice Longbottom
As mentioned in the books and movies, Neville’s parents are tortured by the Death Eaters with the Cruciatus Curse. In the movies, it is implied that they die while they appear in the movies when Ron, Harry and Hermione visit Arthur Weasley at St. Mungo’s Hospital for magical deformities and injuries. However, he does not appear in the movies at all.
5. Winky
Winky the house-elf first appears at the Quidditch World Cup, where he is fired by Barty Crouch Sr., prompting Hermione to crusade for house-elf rights. Winky later turns up at Hogwarts, falls into depression and leaves a series of hints about Crouch. It is eventually revealed that Winky was tasked with taking care of Crouch Jr., a convicted Death Eater who had been estranged from Azkaban and kept in hiding by his father.
6. Gaunts
During the sixth book, ‘Harry Potter and the Half-Blood Prince’, Harry and Dumbledore trace Voldemort’s legacy, childhood and adolescence. But in the film, every piece of Voldemort’s family background and early years is omitted. This means that the story of Voldemort’s ancestor, the Gaunts, remains a mystery to those who haven’t read the books.
7. Andromeda and Ted Tonkaso
Nymphadora Tonks’ parents played a role in helping Order of the Phoenix appear in the movies, but they both dropped out of the movies. Andromeda Tonks is the sister of Bellatrix Lestrange and Narcissa Malfoy, who married Muggle-born Ted Tonks and was disowned by her family. In Harry Potter and the Deathly Hello, Harry and Hagrid escape to the Tonks house before taking a portkey to the burrow, but in the movies, on the run from Voldemort, they head straight to the Weasley family home.
