In "Dawn of the Planet of the Apes," set ten years after a virus decimates humanity, intelligent apes led by Caesar establish a thriving community in the forests of San Francisco. As they seek to live peacefully, a group of surviving humans, desperate for resources, encounters the apes. Tensions rise between the two factions, leading to conflict and misunderstandings. The film explores themes of survival, leadership, and the consequences of violence, ultimately culminating in a battle that tests the fragile coexistence between humans and apes.

In "Dawn of the Planet of the Apes," Caesar is not dead. The film follows Caesar as he leads a group of intelligent apes in a struggle for survival against humans in a post-apocalyptic world. Throughout the film, Caesar faces significant challenges, including conflict with both humans and rival apes. By the end of the film, he survives and remains a pivotal character, setting the stage for further developments in the sequel, "War for the Planet of the Apes."

"Dawn of the Planet of the Apes" is the second film in the rebooted "Planet of the Apes" series, which started with "Rise of the Planet of the Apes" (2011) and continued with "War for the Planet of the Apes" (2017). Therefore, there are three films in this rebooted trilogy: "Rise," "Dawn," and "War."

As of my last update, "Kingdom of the Planet of the Apes" is set to explore new stories within the franchise, taking place many years after "War for the Planet of the Apes." Caesar's son, Cornelius, is not confirmed to appear in the movie. The film aims to introduce new characters and expand the world of the apes. However, specific plot details and character appearances have not been fully disclosed, so it’s advisable to check the latest updates for any new information regarding the film's cast and storyline.
