[1] The movie is based on the Chilean comics character Mampato created in 1971 for the magazine of the same name by Themo Lobos and Eduardo Armstrong, and later reprinted as the comic-book Cucalón, the story for the film being adapted from the seventh adventure in the series: "Mata-ki-te-rangui".

With the help of his time-space belt, he travels back to prehistoric times in search of his friendly caveman companion, Ogú.

In their quest to uncover the mysteries of Rapa Nui, Mampato and Ogú join a rebellion against the Long Ears and their protectors.

After days of adventure, our heroes return home - Ogú to prehistoric times and Mampato back to the present, where only a few minutes have elapsed since he locked himself in his room.

Starting production in 1999, director Alejandro Rojas made a treatment with Themo Lobos and selected the seventh story rather than the first one, because it was based on Easter Island, a world-renowned location (with its famous Moais) best suited for a strong Latin American advertising campaign and as a means to generate non-Chilean interest.
