It was a rather strange career start in movies, Torgaman. First, there was a René Cardona film in 1952 called "El enmascarado de plata" and it was apparently about him - but he was played by another actor.
Then, these two "false starts" in 1958, in another country, and playing (apparently) his own character... but being unnamed in these movies.
And finally, what we can call the "real start" in Mexico some years later...

Do you know why he didn't play himself in the 1952 film? maybe he was too busy with his career in lucha libre... or just not interested in movies?
