Differences between book and film

Hi...there is more differences between book and film....but there are sometimes difference that I get nervous when I watch the Film .

In your opinion, what are they?

(I watched the movie yesterday)

Ok ok I answer to my question :

1) When Harry Potter passes the first test of the dragons and takes the egg, in the hall of Griffyndor rejoices and makes the phenomenon! The book rather is modest, as the character Harry!!

2) For the second test is helped by Neville! In the book instead of Dobby! Dobby always helps Harry, in fact in the last film the scene of his funeral is not so much felt by those who have not read the books.


What do you think?
