Forbidden Planet

Forbidden Planet is a monumental 1950s sci-fi film. Robby the Robot, who appears in this film, became popular and influenced various sci-fi movies, manga, and anime.

A spaceship from Earth traveling through space receives a strange radio signal from a planet called Altair IV. Upon arrival, they find a doctor who had migrated to Altair long ago, living with his daughter while having a robot take care of all his daily needs. The doctor warns the crew, 'There is a monster living on this planet. It is dangerous, so leave,' but when asked, 'Then why are you living here with your daughter?', he does not answer.

One day, the spaceship is attacked by a mysterious 'invisible monster.' When the spaceship deploys a barrier using high-output electromagnetic waves, the monster reveals the outline of a giant, cow-like body upon touching the waves. The captain questions the doctor, but the doctor remains silent. In truth, this planet hides not just a monster, but a certain terrifying secret...

This is the most skillfully crafted sci-fi film made before 2001: A Space Odyssey. The alien landscapes are all sets, but they are well-made. The concept of the invisible monster (commonly known as the Monster from the Id) is particularly well-executed, and its shocking true identity is revealed at the end. This has significantly influenced the works of Kazuo Umezu. To my knowledge, there are three Umezu manga that use the idea of the Monster from the Id.

The scene where the Monster from the Id touches the electromagnetic waves and reveals its form was expressed through animation with the full cooperation of Walt Disney Productions. The animation was handled by Joshua Meador, who animated the escape from the whale in Pinocchio and the magma of the primitive Earth in the 'Rite of Spring' segment of Fantasia.

Also, the spaceship captain is played by a young Leslie Nielsen, known for The Naked Gun.

It seems there were indigenous people on the planet Altair IV, and the doctor settled there to investigate them, but the indigenous people apparently went extinct for some reason, and that reason forms the core of the work. Truly, it is a very well-made sci-fi film.
