As I said elsewhere in the comments, even if I wanted to, I don't have the release forms from the actors, some of whom were professionals trying to get a big break in their careers, and one of whom had worked with Stanley Kubrick in a bit part on Barry Lyndon (I did get signed forms, but they didn't include the internet as it was in its infancy in those days and it didn't occur to me to include it - just cinema, television, etc).
