How many words of a novel can make a movie?

The exact number of words needed for a novel to be adapted into a movie often depended on the scale of production, the complexity of the story, the choice of director and actors, and the production of special effects. Therefore, the length of a novel adapted into a movie could vary greatly. Generally speaking, a medium-sized novel would only need a few thousand to tens of thousands of words if it included the main characters and storyline according to the common narrative techniques and structure. However, if the novel were to contain more plots, more characters, and more complex narrative structures, the length of the novel might be longer. In addition, the length of the novel adapted into a movie also depended on the length of the movie. For example, a 120-minute movie might only require the length of a few novels, while a 160-minute movie might require the length of the entire novel. Therefore, the specific word length of a novel adapted into a movie varied from person to person, and there was no fixed standard.
