A slow, minimalist, somewhat surrealistic and interesting science-fiction drama.
A strange, purple cloud is visibe in the night sky, somewhat near Jupiter. Apparently, a mission has been sent there to investigate. When the film starts, Jakub Prochazka has been on his way on this solo mission for half a year. He is getting closer to the strange cloud.
Slowly losing his mind due to the loneliness of his job, Jakub encounters a strange, spider like fellow passenger on his ship. “Hanus” seems to be an alien life form who is interested in the human condition. Hanus not only becomes some sort of psychiatrist to Jakub, but he also explains what the cloud actually is. In the meanwhile some drama is added when Jakub’s pregnant wife, who remained on earth, has second thoughts about their relationship.
In story and atmosphere, “Spaceman” perhaps holds the middle between “Interstellar” (but not as good and not that complex a story”) and “Ad Astra” (but better).
