MISTAKES
When Harry is in the potions class he is caught writing notes down, we see his neat writing in close up ... but when the camera angle changes we can see that the writing has changed in size to very large letters and quite messy writing.
In the bit where Harry, Ron and Hermione are fighting the troll, when Ron knocks the troll out it falls flat on its face - but when Harry takes his wand out of its nose, its head is facing the right-hand side.
When the troll falls face-down, it appears the wand goes through his head. In the next shot, with his head turned, it's not.
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!
How did Hermione know it was Harry Potter when on Hogwarts Express his scar was covered by his fringe?

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.

When Harry receives his Nimbus 2000, there are not any "Gold" metal protrusions near the thatch of the broom, but as they are approaching the Quidditch field there they are. You can also see them in the window as Harry passes the Quidditch Shop in Diagon Alley.
