The Harry Potter movies certainly did the source material justice. They were Hollywood's biggest event between the years 2001 and 2011, with everybody heading to their local theatre to see The Boy Who Lived in action. Daniel Radcliffe, Rupert Grint, and Emma Watson all won plaudits for their performances as Harry, Ron Weasley, and Hermione Granger, and Warner Bros did a terrific job at staying true to the source material.

That is, for the most part. Some characters didn't resemble their book selves, no matter how brilliant all eight movies are. So we'll now take a look at ten individuals who, according to JK Rowling's novels, didn't look right.

Ron Weasley

Ron Weasley Harry Potter

There's no denying that Grint did a brilliant job at playing Ron. He nailed the sense of humor of the character, often making fans laugh with his outbursts of bad language and worrying persona. We'd say he couldn't have done much more performance-wise but, while that's the case, we still have some complaints.

Grint's version of the youngest Weasley boy wasn't entirely accurate. His nose wasn't overly long and he lacked the freckles that are so often mentioned during Rowling's books. This would have been fairly simple to amend but these were details that weren't deemed important enough to include on the big screen.

Hermione Granger

Hermione Harry Potter

When we think of Hermione, we can't help but think about Watson too. She brought the character to life marvelously, showing just how bossy, demanding, and intelligent she can be. And while her appearance was nailed, for the most part, several things about the character were omitted.

Hermione is meant to have huge front teeth, which she later shrinks down in the Goblet of Fire for her Yule Ball date with Viktor Krum. It would have been tiresome for Watson to keep having fake teeth in her mouth but that should have been done for the first three movies for the sake of accuracy. Instead, Watson was allowed to stick with her normal gnashers.

Horace Slughorn

Horace Slughorn

Horace Slughorn makes his first appearance in the Half-Blood Prince movie, returning to Hogwarts after many years away to take up his old role of Potions Master. Albus Dumbledore has a secret reason for wanting him back, though, believing him to be in possession of a crucial memory that can help in the battle to destroy Lord Voldemort once and for all.

Jim Broadbent took on the character when the blockbuster released back in 2009. However, he looked substantially different in the books. In the sixth novel, Slughorn is described as being a short, round man with a great big mustache. This Slughorn, instead, was taller, not as beefy, and had no mustache whatsoever. If anything, Filius Flitwick from the films looks more like the Potions Master instead.

Lord Voldemort

Lord Voldemort Harry Potter

Again, the movies made just a minor mistake with the character of Lord Voldemort. He looks intimidating during his five appearances in the series, with his snake-like nose, bald head, and skeletal appearance making him look like something from a nightmare. But, surprising as it may sound, the Dark Lord in the books is different.

In the novels, he has bright red eyes. This makes him even scarier and even more horrific but the movies decided not to do anything with this information. David Heyman and Mike Newell later explained the decision by saying they thought giving the villain red eyes would remove too much humanity from him. But we can't help but feel they missed a trick...

Bill Weasley

Bill Weasley only makes a fleeting appearance in the Potter movies, appearing at the starts of the Deathly Hallows: Part 1 and Deathly Hallows: Part 2. His face is somewhat scarred and he explains how he got his wounds following a fight with werewolf Fenrir Greyback, described as a 'nasty piece of work'.

The Bill of the books, however, is horrifically scarred - even more so than the version we saw on the big screen. He ties his hair in a ponytail, rather than just letting it hang, and also wears earrings - much to the annoyance of his mother, Molly. These tweaks would have been easy to do but, given Bill wasn't significant, it doesn't make that much difference.

Petunia Dursley

Aunt Petunia Harry Potter

Petunia Dursley appears for the first time in the Sorcerer's Stone, played by Fiona Shaw. She later appears in four other Potter movies and she's another who has to make the list.

Petunia in the source material is described as having blonde hair, pale eyes, and as having an abnormally long neck. Alas, none of those were present in the blockbusters she appeared in. Shaw was thin like Petunia but, that aside, bore precious little resemblance to the character's initial description.

Sirius Black

Sirius Black Harry Potter

Sirius Black is played by Gary Oldman in the Harry Potter movies. He resembles the character with his shaggy hair, slim body shape, and haunted look from many years in Azkaban. Yet there are still some differences that exist.

Sirius is said to have waxy skin stretched so tightly over his face he looks like a skull, filthy hair that hung all the way down to his elbows, and sunken, sullen eyes that make him look like a corpse. So while Harry's godfather does indeed look rough when we meet him for the first time in the Prisoner of Azkaban, he could have looked even worse.

Alastor Moody

Alastor Moody Harry Potter

Alastor Moody first appears in the Goblet of Fire, or at least the character itself does. Harry spends a whole year in the presence of somebody he thinks is loyal to Albus Dumbledore, but it's then revealed that the man the Boy Who Lived thought was Moody was merely Death Eater Barty Crouch Jr in disguise. The real Alastor had instead been imprisoned in his own trunk.

Moody in the movies has his magical eye attached to a strap, and his nose intact. But these things are different in Rowling's novels. The eye fits into its socket without any support and his nose is far from intact, instead having a huge chunk missing. We admit that would have been pretty scary for younger people to see, although fascinating at the same time.

Rufus Scrimgeour

Rufus Scrimgeour

Rufus Scrimgeour only cameos in the Deathly Hallows: Part 1 movie, appearing at The Burrow to give Harry, Ron, and Hermione contents from Albus Dumbledore's will following his death in the Half-Blood Prince. He's played by Bill Nighy and has long matted hair.

In the source material, though, his description is different. The Minister of Magic is said to resemble an old lion with grey streaks in his mane of tawny hair and bushy eyebrows. Furthermore, he had keen yellowish eyes and wore wire-rimmed spectacles - in addition to being scarred. Nighy's look was too clean and he didn't give off the impression of a man who had fought in many, many battles with dark wizards years previously.

Neville Longbottom

Neville Longbottom Harry Potter

Neville Longbottom starts off the series looking pretty book-accurate, a lack of blonde hair aside. But with Matthew Lewis undergoing quite a transformation, the character did too. And that means that by the time Neville battles in the Deathly Hallows: Part 2, he looks drastically different.

He's tall, lean, and has black hair instead of being short, big-boned, and with blonde hair. Lewis's own changes couldn't be accounted for so it's understandable why the physical aspects were altered. But they could have at least given him a new haircut in order to stay truer to the source material.
