In fact, thanks to God, my father is alive and healthly. He is 64 years old, so he was about 23 when this episodie was filmed.
At this moment I have not any other information to the previous post. I know he was choosen as extra due to his level of Enghish (very strange in Sevilla in the 60s) and because he was a punctual city-gide for some people of the serie.
He had a short phrase in a scene in an hotel bar (I hope this scene is include in the DVD!!).
I have just bought it and in order to mantain the surprise, please understand, I am not going to ask him about details until the DVD will be received. Then I will return with any other information.
