The author’s choice of setting is reflective off of the mood and tone of the book/play/movie and of the characters. Whatever setting is chosen, it impacts the themes because the characters are all in the setting. The characters can develop and gain new information etc. based on what kind of setting they are in. The setting progresses the plot because if the mood of a book is joyful and the setting is dark and ominous, then it would definitely change the whole plot line. For example, if all of the characters were very happy people and they go from a sunny day on the beach to a haunted mansion, their personalities might change with the setting. The authors choice of setting definitely affects the characters, the theme, and the plot.
