Harry Potter
and the Philosopher's Stone

film adaptation

Changes from the Book

major characters and events from the book not included in the film:

plotlines that were twisted in the transition to the screen:

Switching Spells

  • The snake is from Brazil in the book, but bred in captivity but native to Burma in the film. (However, the appearance of the snake in the film seems consistent with the variety that would be found in Brazil.)

  • Dudley and Aunt Petunia are described in the books as blond, but are dark-haired in the film.

  • Draco's initial offer of friendship to Harry takes place on the Hogwarts Express in the book - an encounter during which Scabbers' great moment of biting Goyle's finger occurs - but occurs outside the Great Hall before the Sorting in the film, sans Scabbers.

  • Harry's parents look quite a bit older than they should. They were about 22 when they died, but in the film they look like they're in their mid-thirties at least.

  • Firenze is white-blond with a palomino body in the book, but appears to be dark-haired in the film.

Conjuring spells
additions to the film without direct canon backing:

  • The full-out depiction of Voldemort's attack on Harry and Lily Potter is only in the book in Hagrid's dialogue, but becomes a first-hand depiction of the flashback in the film.

  • Though there is no real description of the Hogwarts uniforms or obvious differentiation in house appearances in the books, the films have added house crests, ties, and prep-school-inspired clothing under the cloaks.

  • Oliver Wood's anecdote that during his first Quidditch match, he took a Bludger to the head two minutes into the game and woke up a week later in the hospital wing.

  • The plaque that proclaims James Potter to be a Seeker, and the non-canon characters R.J.H. King and M.G. McGonagall on it. (The latter cannot be Professor McGonagall, who far from being a teammate of James Potter was one of his teachers.) See PS/f errors for more about this plaque.

    • King, R.J.H.
      Non-canon student at Hogwarts in the late 60s/early 70s. He or she played Quidditch for Gryffindor, and in 1969 won a small plaque which is now part of a trophy in the trophy room.
      NOTE: King's name appears on a wooden shield in the trophy room in PS/f only. Other information on that shield is problematic since it contradicts JKR's statement that James Potter was a Chaser. Therefore King cannot be considered part of the official canon.

  • spells:

  • portraits present in the film but not in the books

    • picture of a little girl who curtsies to the first years on their way up to their common room after the welcoming feast

    • picture of a woman who walks into a room and sits by a bed, in the hospital wing

    • Among the portraits on the shifting staircase is a painting of Anne Boleyn, King Henry VIII's second wife and the mother of Queen Elizabeth I. One of the charges against her when Henry VIII had her tried and executed was that she was a witch.
