Harry Potter and the Philosopher's Stone

Corrected entry: When Harry, Hermione, and Ron go up the stair case, and end up in the third floor, you see there are three floors in view, plus a stair case going down, connected to the last visible floor, so in reality, it really wasn't the third floor.

Correction: In the UK, we don't start numbering right from the bottom. We start with the ground floor, which would be the first floor under the US system, then number as you go upwards. So, our first floor would be the second floor in the US and so forth. As such, the third floor that they refer to would be the fourth floor in US terminology, which fits with what's seen on-screen.


Corrected entry: In the library at night, Harry escapes Filch and Snape by staying hidden under his invisibility cloak, leaving the room through a door. Harry's hand either must have been visible while operating the door handle or the handle itself must have become invisible if Harry would have touched it with his hand wrapped in the cloak. But the door opens without the door handle being pushed down at all. (01:31:35)

Correction: That's because the door wasn't fully closed. All he had to do was push.


Corrected entry: When Hermione petrified Neville, Neville's hands immediately came to his side and he fell, but in Harry Potter and the Chamber of Secrets, when someone was being petrified, they would stay in their original position.

Correction: Hermione put a full body bind curse on him.

Corrected entry: At the end of the film when Hagrid gives Harry the photo album, Harry opens it to the picture on the front. But going by what we've seen from other clips earlier on when his parents died, the picture is chronologically wrong. They died when he was a baby not a toddler, yet in the picture James and Lily are holding a toddler version of Harry.

Correction: Baby Harry was played by The Saunders Triplets who were a year old during the filming of Harry Potter. Same age as baby Harry would have been. They may look big to you, but they are the correct age.

Corrected entry: In Gringott's, after visiting Harry's vault, as they stand in front of vault 713, a cart passes by on the tracks. In order to do this, it almost certainly would have had to jump the cart Harry and Hagrid had been using.

Correction: The fact that you're speaking of Gringotts Wizarding Bank, which is run by Goblins who have many enchantments in place, is in itself evidence that there really is nothing extraordinary about an enchanted cart travelling within the bank's underground passages, on its interlinked series of tracks.

Corrected entry: When Harry is standing on his broomstick to catch the Snitch at the Quidditch scene and then he falls, it is impossible for the Snitch to get in his mouth without its wings cutting Harry's lips.

Correction: How so? We have no idea what the Snitch is made of. The wings could very likely be soft enough to rub right over Harry's lips without leaving a mark.


Correction: When Harry spits the Snitch out of his mouth the wings are all folded up so the Snitch could have very easily folded up its wing after going inside of Harry's mouth.

Corrected entry: Percy Weasley is obviously talking to the Gryffindor first years when they first enter the Gryffindor common room, but there are too many first years. There are 5 boys and 5 girls in each dormitory, so 10 first years in each house, but in the shot there are obviously almost 20 students there, not including Percy. (00:47:30)

Correction: While each room does only fit 5 students at a time, the movie did not state there is only one room for each gender per year. We don't see all of Gryffindor tower and have no way of knowing if there is only one room for first year boys/girls.

Corrected entry: Just after Draco Malfoy was sorted, Ron mentions to Harry that there wasn't a witch or wizard that went bad that wasn't in Slytherin. However, at this point, Sirius Black was believed to be a dark wizard by the whole wizarding community, and was very well known as well, although he was in Gryffindor when he was at Hogwarts.


Correction: However, Ron is a little kid and heard a rumor that he pronounced as fact. But the adult wizarding community knew better.


Corrected entry: After arriving to Hogwarts, just after Draco Malfoy is confronting Harry, Professor McGonagall taps Draco on the shoulder, when turned around, for a split moment you can see the tape that keeps on his wig to cover his brown hair.


Correction: Except he's not wearing a wig; Tom Felton's hair has been dyed platinum blonde ever since he first got the role of Draco Malfoy.


Corrected entry: Just after Ron says, 'Mails here!', we see the owls dropping various packages to Hogwarts students. The very first owl closeup we see is a brown one and s/he is flying to the right. It's carrying a green package. When the owl drops the package and a student catches it, however, the package has turned blue. (00:53:50)


Correction: They are not meant to be the same package. We are shown two tight close-ups of owls - among many other owls, who are delivering/dropping the mail, which merely serve to illustrate this event. The package the first owl releases is green and rectangle, with string tied around the smaller side, and a student catches a larger, blue, square package with string tied around all of its sides. Two shots later we see another owl drop a tan, rectangle package, with a single string and it cuts to yet another student catching an entirely different smaller package. Neither of these are mistakes.

Correction: The stair cases move, it's possible that the banister will wobble.


Corrected entry: In the end credits they say that there are 3 beaters on the Slytherin team. There should only be 2.

Correction: It doesn't even list Slytherin team beaters in the end credits.

Corrected entry: Why didn't Ron just get off the stone horse instead of risking his life by taking the hit the queen gave out?

Correction: Because then he's not playing the part of the knight, and it would end Wizard's Chess. That would then invalidate the challenge and not allow them to pass.


Corrected entry: Watch Neville as he falls - he crashes on his back, but when Madam Hooch comes to him, his on his stomach.

Correction: No, you are quite wrong. When he actually hits the ground we can't see it because the other students stand between Neville and the camera.

Corrected entry: When Harry, Ron, and Hermione are telling Hagrid that Snape is trying to steal the stone, he tells them that Snape helped protect the stone, and 'he's not about to steal it'. So far so good, sticks to the book. However when they actually try to save the stone, Snape's challenge, the logic one with potions, is missing!

Correction: There is no evidence in the film that suggests that each of the teachers did a separate challenge.

Corrected entry: Near the start, Percy says "Boys upstairs and down on your left, girls the same on your right". However, after the three heroes have been to investigate Fluffy and they go back to the dorms, when they reach the top of the stairs Hermione goes to the left and the boys head right. (00:49:30 - 01:03:30)

Correction: Incorrectly regarded as a mistake. The spiral staircase that leads up to the dormitories ends on a landing that is oriented at a 180 degree angle from Percy's position when he speaks the line. Coming up the stairs to the dormitories (and pointing the camera) from the back side (looking over/toward the common room from the landing) means that left and right are reversed from the camera's point of view in the second scene. Harry, Ron and Hermione go into their appropriate dormitories.

Corrected entry: There's no reason whatsoever the trio needed to risk telling Hagrid at nighttime that they knew about the Philosopher's Stone, as it ends up in them getting in trouble. They could have told him immediately after Hermione found out about the Philosopher's Stone in the library. Or if they couldn't find time between classes, they could have waited until tomorrow.

Correction: They are kids, they got excited. It's not a stupidity for a movie to have kids do stupid things. Kids do stupid things, that's why they are kids.


I don't necessarily agree with that. In the book, they had a legitimate reason to sneak out during nighttime as they were trying to smuggle Hagrid's dragon out of Hogwarts without it being seen, which isn't in the film, so there is no reason for them to wait until nighttime to talk to Hagrid about what they know, nor does it explain why Malfoy is there suddenly.


Corrected entry: At the first flying lesson when Malfoy is about to fly, we see Hermione looking up in the sky before Malfoy gets that high. (00:57:55)


Correction: How this can be a mistake? She was simply looking at the sky because she was nervous as she never flew on a broom before.

Corrected entry: In 'Deathly Hallows Part 1', James and Lily Potter's gravestone says they died in 1981. When their deaths are shown in 'Philosopher's Stone', baby Harry is seen wearing a Blue's Clues shirt, but Blue's Clues didn't exist until 1996, 15 years after the Potters' deaths.


Correction: Those are bunny rabbits on his shirt.


Corrected entry: In the reptile house at the zoo, Dudley yells at his parent to come and see what the snake Harry is looking at is doing. The problem is that Dudley is facing the opposite wall when he yells out and hasn't even seen the snakes' enclosure yet.

Correction: The Burmese Python is lying down motionless at the bottom of its enclosure, when Dudley decides it's boring and walks to the exhibit behind Harry. During the conversation with Harry, the snake perks up, raises its head up high, to Harry's shoulder level, then moves about very animatedly when Harry turns to look at the zoo sign and continues talking. The next time we even see Dudley, his head and body are already turned halfway towards Harry's direction, whereupon he shouts for his parents to come see what the snake is doing. It is clear from Dudley's body position that he has just seen the snake's very noticeable actions, as it was speaking to Harry.

Harry Potter and the Philosopher's Stone mistake picture

Continuity mistake: At the snake exhibit, while Harry speaks with the Python the snake's body lies curled over a long wood log and a large rock. In the shot from outside the Python's exhibit, after the glass pane disappears Dudley falls over the rail and the snake is gone, not positioned differently or blocked from view, but altogether gone. In the next overhead shot inside the Python's exhibit, while Dudley falls the snake is back lying on the log and rock, in the very same position as in the previous shots. (00:07:10)

More trivia for Harry Potter and the Philosopher's Stone

Question: I noticed that Harry's scar hurts when he comes close to Professor Quirrell, but why is this not happening when he meets him for the first time in Diagon Alley? Wasn't Voldemort on his head yet?


Chosen answer: Voldemort is not on his head in Diagon Alley as explained in the books. He attaches himself to Quirrell when he learns that Quirrell was unsuccessful in getting the Philosopher's Stone from the vault, in attempt to keep an eye on him.

But in the movie when they met in Diagon Alley, Quirrel refused a handshake because it would kill him.

It's never explained in the movie that that is why he doesn't shake hands. In the books, hagrid says that Quirrel hasn't been right since he met a few vampires in the black forest.
