List Rules Vote up the most glaring and unforgivable plot holes from the Harry Potter movies.

First, let's get one thing out of the way: Harry Potter is arguably the greatest series in literary history. Not surprisingly, the films did not always live up the high standard set by J. K. Rowling. The plot holes in Harry Potter movies are often a result of the filmmakers deviating from the books. And sure, there are some logical inconsistencies in Harry Potter that may or may not have originated in the books themselves, but for the most part, the fault lies with the movies. 

These Harry Potter logic fails perpetrated in the movies might only offend book fans, but that doesn't make them any less egregious. What is Harry doing reading by wand-light in the Dursleys' house, Alfonso Cuarón? What happened to Snape's potion room protecting the Sorcerer's Stone, Chris Columbus? And when it comes to confusing things in the Harry Potter universe, everything with Polyjuice potion might take the cauldron cake. Sometimes it changes your voice; sometimes it doesn't. Either way, that's pretty sloppy filmmaking.

Here are a bunch of Harry Potter plot holes you'll want to obliviate straight out of your memory.

Harry Uses Magic Willy-Nilly Outside Of School

The opening scene of Harry Potter and the Prisoner of Azkaban is unforgivable. In the scene, Harry is in his room at 4 Privet Drive using the Lumos charm to read at night. There's just one problem – he's an underage wizard using magic outside of school, an act that's explicitly forbidden. What's more, he's using magic in a Muggle house. The Ministry of Magic would be on him like young Neville on a chocolate frog.

Does Polyjuice Potion Change Your Voice Or Not?

Characters in the Harry Potter movies use Polyjuice potion numerous times. Whenever they do, they physically transform into someone else, but their voice remains their own. Except for one huge instance: Barty Crouch, Jr.

Given the rules established in the films (and only the films) about voices remaining the same, Mad Eye Moody in Harry Potter and the Goblet of Fire should have, at the very least, a slightly different voice than the real Mad Eye.

Snape's Magical Defense Of The Sorcerer's Stone Is Missing

Snape's Magical Defense Of... is listed (or ranked) 3 on the list Harry Potter Plot Holes You Don't Need A Pensieve To See

In Harry Potter and the Sorcerer's Stone, Harry, Ron, and Hermione suspect Snape of trying to steal the Sorcerer's Stone, but they're told explicitly by Hagrid that he's one of the teachers tasked with guarding it. This heavily implies that he has a magical defense of the stone in place, like the other teachers.

In the book, Snape's defense is a logic test, in which Harry and Hermione have to figure out which potions will kill them, and which will let them move on and back, respectively. This, however, isn't in the film at all. But... Hagrid said Snape's protecting the stone. How?

Movie Dumbledore Is Dumb

Many fans think Richard Harris was an amazing Dumbledore who captured the character perfectly. Michael Gambon, on the other hand... not so much.

The writing of this scene in Harry Potter and the Half-Blood Prince is probably the real culprit, but nothing Dumbledore says is consistent with the book. First, after they learn that a young Tom Riddle was indeed seeking guidance on making multiple horcruxes, Dumbledore says, "This beyond anything I ever imagined." Uh, no it isn't. In the novel, it's precisely what Dumbledore imagines. He had actually suspected Riddle's diary was a horcrux all along, and that there might be more given how careless he was with it.

Then Dumbledore goes on to say the horcruxes "could be anything. The most commonplace of objects." Wrong again. They are only objects Voldemort viewed as extremely significant or important, another thing book Dumbledore understood about him.
