Matt Reeves directed this 2014 sequel, set ten years after a devastating virus, where Caesar leads a growing nation of intelligent apes who encounter human survivors in post-apocalyptic San Francisco, leading to an inevitable clash for dominance. What is this movie called?

The movie described is indeed "Dawn of the Planet of the Apes." Directed by Matt Reeves and released in 2014, this film is the second installment in the rebooted Planet of the Apes series, following "Rise of the Planet of the Apes" (2011). The story picks up a decade after a devastating "Simian Flu" pandemic has decimated the human population, leaving only a small percentage immune. In this post-apocalyptic world, Caesar, the intelligent ape introduced in the previous film, has established and now leads a thriving and growing nation of genetically evolved apes in the Muir Woods, just outside of San Francisco.

The fragile peace of the ape colony is shattered when a group of human survivors, attempting to restore power to their community in the ruins of San Francisco, ventures into the apes' territory to reactivate a hydroelectric dam. This encounter ignites tensions between the two species, as mistrust and fear quickly escalate. Despite Caesar's efforts to maintain peace and understanding, particularly with the human leader Malcolm, the presence of radical elements on both sides pushes them towards an inevitable and tragic conflict for dominance over the Earth.

"Dawn of the Planet of the Apes" was widely praised by critics for its compelling storytelling, impressive visual effects—especially the motion-capture performance of Andy Serkis as Caesar—and its exploration of complex themes like leadership, empathy, and the struggle for survival. The film delves into the internal politics of both the ape and human societies, showcasing how fear and prejudice can lead to war even when leaders strive for coexistence. It stands as a significant entry in the science fiction genre, offering a poignant look at what it means to be intelligent and to fight for one's home and family.
