Here are some similar things that were in the book and the movie. In the book Opal says to Dunlap and Stevie run off you bald headed babies! Here’s another similarity: Otis goes to jail. Another similarity was that Amanda loses her brother Carson. The last similarity is that Carson drowns when he is 5 years old.
Here are some differences from the book and the movie. In the book Dunlap vs opal in a race but in the movie Dunlap vs Stevie. In the book Gloria Dump is nice but in the movie Gloria Dump is more what Stevie and Dunlap say a “witch”. Dunlap is nicer in the movie then the book.
