La mujer con botas rojas (La femme aux bottes rouges) (1974) as Monsieur Piretti, only seen in a flashback vision where he is cutting his throat.

Beatriz (1976) credited in the role of "Pelos".

I assume he must be one of the men in the first image, but none of them are ever called by the names in the credits and I can't say that any of them looks much like Peral. My best guess is the one in the second image, though if it is him then he is obviously wearing a wig. Due to the uncertainty I am marking this as an uncertain identification.
