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.
