I saw this movie yesterday, and although the movie register of the DB says it is filmed in color (eastman color), this movie was aired in black and white.
Do you know if eastmancolor is a technique to add color to B&W movies??? or the data of the DB are wrong?

I don't know if this helps but no, Eastmancolor does not work that way, it is a high-quality colo rnegative. The thing with this film is that apparently, that negative is lost, and now it only survives in B&W copies.
I'm not sure if the recently discovered version of "El Vampiro y el Sexo" (the alternate version of this film) is in color or not.
