7 Harry Potter Moments That Are So Much Better In The Film

7. Neville Gives Harry The Gillyweed

In the books, it's Dobby who gives Harry the Gillyweed, and this change acts as an important step in Neville's transformation from zero to hero that we don't get in the books.

In the book, seemingly out of nowhere, the house elf arrives minutes before the task is due to begin and hands the aforementioned plant to Harry. In the film, though, it is herbology expert and fellow Gryffindor Neville Longbottom who comes to the rescue.

In both instances, the disguised Bartemius Crouch Jr. has given Longbottom the knowledge to help Harry overcome this challenge. In the book, however, Rowling plays up the fact that Harry is too stubborn to ask for help and Crouch is forced to lead Dobby into helping the boy wizard. But the film gives Neville this chance to shine.

As Potter fans will know, Neville Longbottom’s transformation is the most drastic in the entire series as he goes from bumbling idiot to true Gryffindor (more on this later). This moment in the film is the perfect mid-point in his metamorphosis as it allows Neville prove his worth to Harry early on and, for that, the film’s version of events is superior.
