The three images here come from a You Tube documentary on Spanish wrestlers and are reportedly from Hollywood films in which Juan appeared in the 1930's. The Spanish language titles mentioned do not coincide with any known titles, so I could not work out what films they are from, though the first image seems like it could be a match for his reported appearance in
Anything Goes (1936) as Guard with halberd. The third image, while certainly Juan, does not seem so much like a film still, so may not be.
