Cazadores De Espias (1969)

Two groups of international spies, one led by the mysterious Mr. X and the other by the evil Sylvana (Maura Monti), compete for the control of a top-secret material that can be used to construct spacecraft for sale to the highest bidder. To fake his own death, Mr. X allows Sylvana’s men to kill his twin brother. Mr. X also arranges the murder of secret agent Ramiro, who was investigating the case. Ramiro’s twin brother, Ricardo (both played by Carlos East), avenges his brother’s death by taking up the pursuit of Mr. X. Also stars Eleazar García and Leonorilda Ochoa. (In Spanish language).
