MATRIX

Matrix use a version of the brain in a tray. In this movie, the human being  are aisled in urns. An informatic programme called Matrix is able to conect every brains and recreate a world with relationships between them. The computers that control the planet, need to keep the humans alive because they`re their energy source and with the program Matrix they entretain them.
There's a group of people who escaped the trays and they disconnected themselves from Matrix. They try to defeat the machines, but they aren't able until they find Neo, the one. He, after defeating the computers, makes an error in the system and he takes over the control and the humans are in charge again.
This movie has a relation with the Cavern Mith, due to the fact that they have the same meaning and the components are very similar, for example: the slaves of the cavern would be the humans inside the trays, and the cavern would be Matrix. The fire that is in the cavern could be compared with the agents, and the chains with the weapons. Finally there is also a relation between the exterior world and Zion (from Matrix). The last similar thing would be the freeing of one of the men in of the cavern that came back to rescue the others and the success of Neo in liberating everyone from the machines.
