Even the best of us make mistakes, but the Harry Potter film made quite a few! Here are a selection of mistakes that have been spotted by the fans and the sharp eyed.

Wood tells Harry that if he catches the snitch the game ends and the team wins. But you don't necessarily win. The Snitch is worth 150 points and if the other team is ahead by more that 150 points you lose. The Quidditch Final match in the Goblet of Fire is an example.

At the start of term feast, after Harry is sorted into Gryffindor, he sits down on the right side of the table next to Ron. When the feast appears, Harry is on the other side of the table, next to Hermione.

When the three children get past Fluffy because the harp is playing, as Fluffy wakes he dribbles on Ron's shoulder. However, when they fall down into the Devil's Snare, his shirt is completely dry.

In the sorting ceremony, we see Susan Bones, the girl with long curly hair, was sorted into Hufflepuff House. Later, in Professor Snape's Potion class, we see Susan was sitting behind Harry when Snape questions him. Only Gryffindor and Slytherin are attending in that class together - Susan was in the wrong class!

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!

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.

In the scene when Harry, Ron, and Hermione visit Hagrid, Malfoy is visible through the window. He appears to be eye level with the window and is shown turning and running away. When the camera zooms out later in the film, the same window that Malfoy is supposedly looking through is far too high for anybody to see through without a ladder. He obviously didn't have a ladder or he would have fallen off it when he turned to run away

At the end of the movie Hagrid gives Harry the photo album. After Harry looks at it and tells Hagrid goodbye, he walks back to the train with his hands at his side and there is no sign of the album in either hand.

When the troll is about to swing at Harry for the third time with his club, Ron levitates his club in mid-air. When the club falls, it hits the trolls head with a loud thunk, then falls to the ground. But you never hear any sound of the club hitting the ground.

On the train to Hogwarts, Hermione tells Harry and Ron that they need to get their school clothes on, as they will arrive soon. It is daytime outside. Yet the train arrives at Hogsmeade Station in the middle of the night.

In the scene when Harry is sitting in the dark looking at the mirror, just before Dumbledore comes from behind to talk to him, you can easily see the shadow of a camera man and camera on the wall.

Last scene of the Hogwarts Express: the trees to the left of the screen are blowing madly in the wind, while the trees to the right aren't moving at all.

When Hagrid hands the goblin the letter about "you know what", the letter has crinkles on the edges, but when the goblin takes a look at it, it's all neat. Then when he looks up at Hagrid, it's crinkly again.

In the scene where Hermione, Ron and Harry are returning to Gryffindor's tower room after being in the third floor room for the first time, you are able to see the feet of one of the crew. It happens just as they are passing through the picture hole, where Harry turns a couple of times to check that the "door" is closing. And it is in fact, because someone is walking behind it and pushing it shut, since the picture hangs several inches off the floor.

In the scene in Diagon alley when Harry first enters there are some witches on the left hand side of the screen looking at what appears to be large lollypops and Harry walks past them. The camera angle changes and Harry walks past them again.

At one stage in the sea hut scene, Harry is standing beside the BARE wall of the fireplace. The camera then goes to Hagrid, who turns and pulls the broken door down saying "Unless you'd rather stay, of course?". The camera then goes back to Harry, who is stil by the wall that now shows his coat is hanging right there beside him, which Harry then grabs on his way out.

In the overhead shot of Olivander's wand shop, you can see three wands on his desk that are in a fanned out position. Then when Olivander is handing wands out to Harry, the wands are straightened out.

When Professor Quirrel runs into the dining hall, to tell everyone about the troll, he faints. It is shown that he falls down face first, but when it shows all the students running, Quirrel is suddenly flipped over, lying on his back.

After final exams, we see that Hermione is wearing her grey school knee socks, but when the three of them run to Hagrid's house, we can see that Hermione is wearing white pantyhose.

When professor turns from a cat back into a human she isn't wearing her glasses, but in the next shot she is wearing them!

When Ron first hits the floor after being knocked off the chess horse, his eyes are open. He quickly shuts them, but it's pretty obvious.

When Harry and Ron are sat on the train, Ron's hair begins with a centre parting, but soon changes to a side parting.

When Quirrell reports that there is a troll in the dungeon then faints he is laying one direction, but a few seconds later from a different shot he is laying the opposite direction.

When Harry, Ron, and Hermoine get off the stairs (which have just moved) onto the third floor, the stairs bounce, clearly illustrating that they are not made of the hard stone they appear to be.

At one point near the end of the film, the camera zooms past the Quidditch Pitch and towards Hogwarts. It only shows the hoops, not the stands around the Pitch.
