What would be difficult while making The Book Thief into a movie

One of the biggest challenges the filmmaker would encounter would be adding the side notes that we see all throughout the book. The side notes that act as a pause of sorts from the reading add detail, meaning, and depth to the reading. The side notes bring more detail to the story. I as a filmmaker would have trouble deciding how i wanted to go about adding those notes into the movie; they can't be taken out because they carry a lot of information that is important to know to understand the book.

Some scenes that must be kept are she is taking the book from the fire and it begins to burn her chest, the scene where Liesel sees all the books in the mayors house, and the scene where papa is trading his cigs for books for Liesel to read. These scenes are a must to keep because it shows what's going on in that time period and shows the connection papa has for Liesel. Without the scene where she is taking the book out of the fire and putting it into her shirt, the movie viewers and the readers who have read the book and are seeing the movie will be missing a essiental part.

A scene that I would cut would be when papa's son run's away. I would cut this scene because it has no real connection to the rest of the book.
