Los astronautas (English: The Astronauts) is a 1964 Mexican comic science fiction film directed by Miguel Zacarías and starring the double act Viruta y Capulina, performed by Marco Antonio Campos and Gaspar Henaine.
In the women-ruled planet of Venus, the Union Leader of the Oppressed Husbands Syndicate wants to revert the power of leadership back to the men and threatens to initiate a strike if his will is not heard.
Therefore, she sends Lieutenant Laúr and Sergeant Rauna on a mission to choose two male earthlings who can prove to be more useful than Venusian men, so that they can bring more of them to Venus.
When Laúr and Rauna choose Viruta and Capulina, two amateur singers who work in a gymnasium, they are intercepted by their constant rivals the Martians who claim that Earth is a satellite of Mars and therefore it should not be intruded by Venusians.
