First and foremost, book trailers are not movie trailers, which can impact creative decisions when developing a book trailer. While book trailers can be an effective advertising tool, it's important to understand the audience. As screenwriter, Brian Dillon, advises, authors should avoid being too specific with dialogue or characters and focus on capturing the tone and heart of the story. The book trailer should convey the plot, but without giving too much away. He recommends that authors also avoid picking out specific scenes to show in a book trailer, as this may be misleading to the audience since readers tend to formulate their own ideas about characters and scenes.
