~1Sorcerers Stone 1.Well it didn't show in the movie When the students where put into their different classes the hat didnt go all the way over their head.
~2The Chamber of Secrets 1.While on the way to Hogwarts in the flying car in the book Ron notices the train out of the window, but in the film Ron lands the car on the tracks to find the train nearly hitting them.
2.Half headless Nicks Deathday party is completely missed from the film
3.The final major difference is the effects of the Poly juice Potion. In the book it gives the drinker the exact same appearance , voice and Disabilities for example bad eyesight. In the film Ron and Harry have to imitate Crabbe and Goyle’s voices.
~3The Prisoner from Azkabaned 1.
1.Due to this book being the longest at the time some things had to be cut, for example the back story of Sirius Black wasn’t mentioned only his escape and there is no mention of the Fidelius Charm (hides locations from all who don’t know where it is) this is quite a big deal because
2.Then in the film is doesn’t show how Sirius betrayed the Potters even though he didn't.
~4The Goblet of Fire 1. In the book the Weasleys go to Harry’s Uncle’s house to collect him blowing up their living room and the Weasley twins giving Harry’s cousin a pig tail is completly abandoned.
2.In the film he wakes up after Hermione wakes him in The Burrow.
It also completely leaves out Hermione’s group S.P.E.W (Society for the Promtion of Elfish Welfare) after seeing them in the Hogwarts kitchen.
3.While I mention it there is no appearence of any house elf.
4.The segment where Dobby gives Harry the Gillyweed in the book is replaced by Neville giving it to him in the film
~5Order of the Phoenix
1.The first difference would be the complete absence of the wizarding sport of Quidditch. Ron’s part of joining the team as keeper is completely missed
2.The house elf Kreacher played a bigger part in the book as he was shown during only 2 occasions in the film
3.Rita Skeeter is missed out when Hermione, in the book blackmails her to make sure she published true articles about Harry when The Daily Prophet is reporting lies.
