Specifically I wanted to get my grandad's story about his time in the partisan/antifascist movement and then after the war him being imprisoned as Stalin spy effectively becoming persona non grata. The whole story is one of betrayal, comeback and then mercy displayed towards the accusers. What I found fascinating about this is the humanity my grandad kept, that still guides me today.
I would be interested in reading a guide on how to conduct this kind of interviews, so if you have one, please share. I was even thinking of paying someone from film school to do it.
