This old man sould be Gian Paolo or Gianpaolo or Giampaolo Rosmino. This immage is from: Ercole e la regina di Lidia. He wrote too a book "Sette demoni in corpo" (1973). I don't thought that he is it, but i hoped it!
Today I am happy to reveal to you that this actor's name is UMBERTO SALOMONE! Identified due to a credited role in the fotoromanzo I Fotoromanzi Giganti del Settimo Cielo N. 21: "Leggenda d'amore" (published 15 June 1964)!
