Planet of the Apes is a 2001 American science fiction action adventure film directed by Tim Burton from a screenplay by William Broyles Jr., Lawrence Konner, and Mark Rosenthal. The sixth installment in the Planet of the Apes film series, it is loosely based on the 1963 novel of the same name by Pierre Boulle and serves as a remake of the 1968 film version. The film stars Mark Wahlberg, Tim Roth, Helena Bonham Carter, Michael Clarke Duncan, Kris Kristofferson, Estella Warren, and Paul Giamatti. It tells the story of astronaut Leo Davidson (Wahlberg) crash-landing on a planet inhabited by intelligent apes. The apes treat humans as slaves, but with the help of an ape named Ari (Bonham Carter), Leo starts a rebellion as he seeks to return.

Development for a Planet of the Apes remake started as far back as 1988 with Adam Rifkin. His project nearly reached the pre-production stage before being canceled. Terry Hayes’s script, titled Return of the Apes, would have starred Arnold Schwarzenegger, under the direction of Phillip Noyce. Oliver Stone, Don Murphy, and Jane Hamsher were set to produce. Creative differences ensued between Hayes and 20th Century Fox. Chris Columbus, Sam Hamm, James Cameron, Peter Jackson, and the Hughes brothers later became involved. With Broyles Jr.’s script, Burton was hired as director, and the film was put into active development. Konner and Rosenthal rewrote the script, and filming took place from November 2000 to April 2001.

In 2029, aboard the United States Air Force space station Oberon, Leo Davidson works closely with apes who are trained for space missions. His favorite ape co-worker is a chimpanzee named Pericles. With a deadly electromagnetic storm approaching the station, a small space pod piloted by Pericles is used to probe the storm. Pericles’s pod heads into the storm and disappears. Leo takes a second pod to find Pericles. Entering the storm, Leo loses contact with the Oberon, and in 5021 A.D., crashes on a planet called Ashlar. He learns that the world is ruled by intelligent apes who treat humans as slaves.

Leo meets a female chimpanzee named Ari, who protests the mistreatment humans receive. Ari decides to buy Leo and a female slave named Daena to have them work as servants in the house of her father, Senator Sandar. Leo escapes his cage and frees other humans. Limbo, an orangutan trader in captured humans, sees them but is taken prisoner to ensure his silence. The murderous General Thade and his gorilla junior, Colonel Attar, march ape warriors to pursue the humans. Leo discovers Calima, the forbidden, but holy temple of “Semos”, the first ape, whom the apes revere as a god.

The Oberon’s log reveals that the apes on board, led by Semos, organized a mutiny and took over the vessel after it crashed. The human and ape survivors of the struggle left the ship, and their descendants are the people Leo has encountered since landing. The apes arrive and attack the humans who have gathered to see Leo, although he evens the odds when he uses the Oberon’s last fragments of fuel to fire a final blast at the first wave of apes. The battle stops when a familiar vehicle descends from the sky, which Leo immediately identifies as the pod piloted by Pericles, the chimpanzee astronaut who was pushed in time as Leo was and had just now found his way to the planet, the electromagnetic storm releasing people from it in an opposite direction in time to their entrance because they were traveling backward not forward in time. When Pericles lands and the pod opens, the apes bow, interpreting his arrival as the return of Semos, and hostilities between humans and apes suddenly cease.

Pericles runs into the wreck of the Oberon and Leo runs after him, followed by General Thade. Thade and Leo fight. Pericles tries to help Leo, but Thade throws him hard against a wall. Thade takes Leo’s gun from him and tries to fire it at Leo. Leo sees that Thade is within the pilot’s deck and closes the automatic door, trapping Thade inside. Thade fires the gun repeatedly at the door, but the ricochets create sparks that scare Thade, who huddles under a control panel. Deciding to escape Ashlar and return to Earth, Leo gives Pericles to Ari, who promises to look after him. After saying farewell to Ari and Daena, Leo climbs aboard Pericles’s undamaged pod and travels through the same electromagnetic storm.
