DC editor Carmine Infantino had tried to acquire the license to publish Planet of the Apes comic books. When this failed to happen, he asked Jack Kirby for a series with a similar concept. Kirby had not seen the films but he knew the rough outline and he had also created a very similar story, “The Last Enemy!”, in Harvey Comics‘ Alarming Tales that predated the original Planet of the Apes novel. He also had an unused comic strip he created in 1956, titled Kamandi of the Caves. Kirby brought all those elements together to create Kamandi. Although his initial plan was to not work on the comic books themselves, the cancellation of Forever People freed him up to do so.
