The Rise of the Planet of the Apes series was seen as a prequel to the Planet of the Apes series because there were some connections and similarities between them. The Planet of the Apes series was a series of science fiction novels by the Australia science fiction writer Isaac Asimov, which mainly talked about the conflict and cooperation between humans and apes. His first novel, Planet of the Apes I, was first published in 1962. His subsequent works included Planet of the Apes II, Planet of the Apes III, and Planet of the Apes IV. The movie Rise of the Planet of the Apes series was adapted from the science fiction film and novel of the same name. It mainly talked about the new civilization established by humans on the planet of apes and the struggle and cooperation between apes. Therefore, it could be said that the Rise of the Planet of the Apes series was a prequel to the Planet of the Apes series because they were all based on the same sci-fi background and storyline. The apes in Rise of the Planet of the Apes and Planet of the Apes also had some similarities, such as their appearance, intelligence, and abilities. These similarities also increased the connection between the Rise of the Planet of the Apes series and the Planet of the Apes series.
