Extremely Loud and Incredibly Close
IRP by Kayla Boyer
Key Difference #1
The movie completely deleted the character Mr. Black. In the book, Mr. Black travels around the city with Oskar and helps him find the thing that could be opened with the key that his father left behind. In the movie Oskar's grandfather is the one that helped him out. The lack of this character helped Oskar build a relationship with his grandfather.
Key Difference #2
This also has to do with Oskar's grandfather. The movie eliminated the grandmother and the grandfather's narration. The movie portrayed them as minor roles, which was what they should have been. The grandparents were not a very important part of the novel which is why it was a good idea to delete their whole narration. Oskar's story is the story that the audience is focused on because of the elimination.
