I did not see this one: Ulysses and the Stars (1976)

Loved it when I was a child. But I will give you a few excellent Russian movies:

Duelist https://www.imdb.com/title/tt5282006/

Kollector https://www.imdb.com/title/tt5031998/

Mermaid (more a girls movie but underrated in my opinion) https://www.imdb.com/title/tt7162390/
