The Fantastic Journey(1977)

With many of the original party returned to their own time, Varian, Scott and Fred find themselves caught up in the machinations of a being called The Source, which has enslaved the inhabitants of the city of Atlantium, built by the survivors of the original Atlantis. The Source plans to us Scott's life force to regenerate itself. The trio are aided by Liana, who reveals that she is half alien.

The travelers are separated by a red cloud which leaves Liana as the 'guest' of Jonathan Willoway, who is the master of a utopian community of golden-garbed androids, and the others trapped in a dark swamp surrounded by green-skinned humanoids. Willoway tries to convince Liana to marry him while Fred's medical skills prove invaluable in discovering the truth.

The travelers arrive in a new zone with Greek ruins and meet a young boy who has escaped from a community inhabited solely by children led by the bullying teenager Alpha.

An alien dictator, Tarant, is planning to invade other time zones and conquer the island. Willoway pretends to agree with him so that he can learn Tarant's secrets. Meanwhile, Liana takes pity on an abused furry creature called the Nefring.

Varian, under the influence of a love drug, meets a woman named Gwenith from a religious community in a geologically unstable zone. When the others arrive Varian reveals he's about to get married. They soon discover that the community fanatically worships a volcano god called Vatticus, who demands human sacrifices.

Arriving at a seemingly abandoned 20th century carnival, the travelers become part of a game played by an ancient Greek sorcerer named Apollonius who, with the help of two assistants, plans to possess Willoway's body so that he can escape his imprisonment.

The travelers encounter a city where the women are subservient to brutish male authority. The women reprogram the AI controlling the society. Using the now unbalanced computer they imprison the males in a strange black void, and Liana pretends to join their cause.

A mysterious rider guides the group to an old house. The travelers – minus Liana – quest for an object that will assist their search for Evoland, and a strange couple conjures illusions drawn from their deepest fears.

A prison craft from Earth's future crash lands in the area where the travelers are resting, releasing two prisoners, a convicted murderer and a thief, into a community of stranded humanoid aliens that does not comprehend violence or the concept of doors and locks. With a killer on the loose scheming to abscond with an orb that gives the aliens psychokinetic powers, Varian and the others must deal with him and protect the pacifists.
