For example, the fourth movie, the Goblet of Fire, is completely devoid of the house elves and Hermione's SPEW efforts. Instead of Dobby giving Harry the Gilley-weed, Neville gives it to him. Maybe the house elves aren't going to play much of a role in the final book.
According to the fan sites like The Leaky Cauldron and Mugglenet, she is consulted however, the directors/producers/script writers can choose whether or not to accept her suggestions.
One example: For this movie the script writers had originally written “one character” completely out of the movie. JK Rowling told them that while it ultimately was there choice to write out “this particular” character, they would have a difficult time explaining certain events in the final movie.
Since I have not yet seen this movie, I cannot venture a guess as to which “one character” they might be referring to.
“One question I have regarding the movies is whether JK Rowling has approved the scripts and the changes from the books.”
Here Ms. Rowling. Here’s the check, now you be on your way.
This was the primary reason for my thread. Either the last two movies will be a complete mess in terms of storyline OR fans are way, way off base in predicting important plot lines.
JK Rowling has said that Harry having Lily's eyes is important but that has also been fairly well ignored in the movie.
