El Santo character is actually based on a true person : Rodolfo Guzmán Huerta (1917 -1984), known profesionally as El Santo or in English The Saint, was a Mexican Luchador enmascarado (Spanish for masked professional wrestler), actor and folk hero. In 1952, the artist and editor José Cruz started a Santo comic book, turning Santo into the first and foremost character in Mexican popular literature, his popularity only rivalled in the 1960s by the legendary Kalimán character. The Santo comic book series ran continuously for 35 years, ending in 1987. Also in 1952, a superhero motion picture serial was made entitled The Man in the Silver Mask, which was supposed to star Santo, but he declined to appear in it, because he thought it would fail commercially. The film was made instead with well-known luchador El Médico Asesino in the lead role, wearing a white mask similar to Santo's silver one. A villain named "The Silver-Masked Man" was introduced into the plot at the last minute, thus the title of the film strangely became a reference to the villain, not the hero. In 1958, Fernando Osés, a wrestler and actor, invited Santo to work in movies, and although Santo was unwilling to give up his wrestling career, he accepted, planning to do both at the same time. Oses was planning on playing the hero in these two films, with Santo appearing as his costumed sidekick, "El Enmascarado". Fernando Osés and Enrique Zambrano wrote the scripts for the first two movies, el Cerebro del Mal (The Evil Brain) and Hombres Infernales (The Infernal Men), both made in 1958, and directed by Joselito Rodríguez. Filming was done in Cuba, and ended just the day before Fidel Castro entered Havana and declared the victory of the revolution. Santo played a masked superhero-type sidekick to the main hero (who was called El Incognito) in these two films, and was not the main character . The films apparently could not find a distributor for several years. Santo's film career really took off in 1961 with his third movie "Santo vs The Zombies." Santo was given the starring role with this film, and was shown for the first time as a professional wrestler moonlighting as a superhero. When Santo's film career took off in 1961, the producers of the first two films slyly entered Santo's name into the titles and finally got them released. Santo eventually wound up appearing in 52 lucha libre films in all (two of which were just cameo appearances). The style of the movies was essentially the same throughout the series, with Santo as a superhero fighting supernatural creatures, evil scientists, various criminals/ secret agents and so on. The tones were reminiscent of U. S. B-movies and TV shows, perhaps most similar to the old Republic Pictures serials of the 1940s. Many of the later films depicted Santo in simulated sex scenes during which he continued to wear the mask. His best-known movie outside of Mexico is also considered one of his best, 1962's Santo vs. Las Mujeres Vampiro (Santo vs. The Vampire Women), which was also featured in an episode of Mystery Science Theater 3000 .In this movie, the production values were better, and there was an attempt at creating more of a mythos and background for Santo, as the last of a long line of superheroes. It was an enormous success at the box office. Only four of the 52 Santo films were ever dubbed into English, the other 48 being only available in Spanish. The English-dubbed Mexican films of that time period were imported to the United States through the efforts of K. Gordon Murray who changed the name of Santo to "Samson" for some of his releases. Most of Murray's imported Mexi-films went directly to late-night American TV. Santo's most financially successful film was The Mummies of Guanajuato (1970), which co-starred Blue Demon and Mil Mascaras. The Santo film series inspired the production of similar series of movies starring other well-known luchadores such as Blue Demon, Mil Mascaras, Superzan, and the Wrestling Women (aka Las Luchadoras), among others. Santo even co-starred with Blue Demon and Mil Mascaras in several of his movies. When Blue Demon invited Santo to co-star with him and Mil Mascaras in the "Champions of Justice" movie trilogy, however, Santo was too busy making other films to participate. By 1977, the masked wrestler film craze had practically died off, but Santo continued to appear in more films over the next few years. His last film was Fury of the Karate Experts, shot in Florida in 1982, the same year he retired from the ring. Seventeen years after Santo's death, his real-life son played the lead role in a brand new Santo movie called Infraterrestre (2001), which co-starred Mexican wrestler Blue Panther.
