Difference between movie and the book

I want to talk about the difference between movie and the book. In the movie, what got my attention is there wasn`t a lady whose name is Mrs.Rainwater. But in the book, this was totally different, there was a lady whose name is Mrs.Rainwater and also she was trying to buy the girdle. In my opinion this made the film, lighter and more fluid. If this scene would be in the film, it might`ve became long and boring.Finally this idea made the movie better. For me, I always prefer enjoyable and fluid movies.
