20th Century Fox president Craig Baumgarten was impressed with Adam Rifkin's filmmaking with Never on Tuesday. In 1988, Rifkin was brought in the studio to pitch ideas for films. Rifkin, being a fan of the 1968 Planet of the Apes felt it was best to continue the film series. "Having independent film experience, I promised I could write and direct a huge-looking film for a reasonable price and budget, like Aliens." Fox commissioned Rifkin to write what amounted to a sequel, "but not a sequel to the fifth film, an alternate sequel to the first film". He took influences from Spartacus, with the storyline being "the ape empire had reached its Roman era. A descendant of Charlton Heston's character named Duke would eventually lead a human slave revolt against the oppressive Romanesque apes, led by General Izan. A real sword and sandal spectacular, monkey style. Gladiator did the same movie without the ape costumes."
