Caltiki – The Immortal Monster (Italian: Caltiki, il mostro immortale) is a 1959 black-and-white science fiction-horror film with similarities to The Blob that was released in the previous year. The film's storyline concerns a team of archaeologists investigating Mayan ruins, who come across a creature that is a shapeless, amorphous blob. They manage to defeat it using fire, while keeping a sample of the creature. Meanwhile, a comet, which previously passed near the Earth around the time of the collapse of the Mayan civilization, is due to return, raising the possibility of a connection between the creature and the comet. After the success of their film Hercules (1958), Galatea Film began production on films in other genres that they hoped would entice the international market, which led to Riccardo Freda being hired to direct Caltiki – The Immortal Monster. Freda left the project during filming, later explaining that he wanted to give his friend Mario Bava, who had been hired as the film's cinematographer and special effects artist, a chance to direct and earn more on the project.
