Despite being portrayed as a secondary character and a close friend to Harry Potter, Hermione Granger holds significant screen time across the seven films of the saga. She accompanies the young wizard through various adventures, often putting her life on the line to assist him in his quests. However, the films overlook certain aspects of her personality and alter her appearance as described by J.K. Rowling in the books.
The Formation of S.P.E.W.
One critical omission from the film adaptation of Harry Potter and the Goblet of Fire is Hermione’s advocacy for House Elves and the establishment of S.P.E.W. (the Society for the Promotion of Elfish Welfare). A significant chapter is dedicated to her efforts in aiding this oppressed race. Hermione founds S.P.E.W. after witnessing the humiliation of the elf Winky, who is dismissed by Barty Crouch Sr. Driven by her compassion, she launches a widespread awareness campaign among her peers, distributing hats and socks for the elves to find. This side of her socially-conscious character is unfortunately missed in the film, which opts to focus on the Triwizard Tournament instead.
Altered Appearance and Features
While Daniel Radcliffe (Harry Potter) and Rupert Grint (Ron Weasley) closely resemble their character descriptions, Emma Watson’s portrayal of Hermione deviates significantly. J.K. Rowling characterizes Hermione as a girl with thick, frizzy hair and prominent front teeth, presenting a more disheveled appearance. As Emma Watson has matured, this contrast has become even more pronounced, particularly since the early films depicted her character traits more accurately.
In Harry Potter and the Goblet of Fire, her dental issues come to the forefront. After Draco Malfoy casts a spell that causes her teeth to grow excessively, she visits Madam Pomfrey for treatment. Taking the opportunity, Hermione requests that her teeth be reduced even more than their original size.
A Dislike for Broomsticks and Quidditch
Although Hermione excels in most of her subjects at Hogwarts, she is notably uncomfortable during flying lessons and has little fondness for Quidditch—a fact that remains largely unmentioned in the films. While she is absent from the Quidditch games and tends to appear anxious in the stands, her discomfort is rooted in her first flying lesson, as detailed in Harry Potter and the Philosopher’s Stone. Rowling describes Hermione as struggling to take off properly and feeling uneasy about flying in the air, showing no enthusiasm for Gryffindor’s matches. This is illustrated further in Harry Potter and the Order of the Phoenix, where she often skips the games altogether.
