For those unfamiliar with the El Santo phenomenon, you can either read about it in depth here, or read my brief sum up here: The man who would become El Santo, the most famous masked luchadore of Mexican wrestling, began wrestling in the mid 1930s. In 1942 he answered the call of his famous Silver Mask, and his popularity grew until it became a genuine cult phenomenon. This was largely fuelled by a penchant for being presented as a peasant hero, fighting against other wrestlers embodying corrupt politicians, drug lords, and American imperialists. After a bout of successful comic books, he took to the Mexican B-movie screen in 1958 with Santo vs. The Evil Brain.
I've devoured all of the El Santo movies Gen X has in stock - which is a reasonable 6 or 7 out of an astonishing total of 52 film appearances - in chronological order. The first on my delirious journey into lucha libre was Santo and the Treasure of Dracula. As Campy as I could have hoped, but a little on the dull side.
So: Not the best in Santo's saga, but seeing him as a prominent scientist is a hilarious wonder.
