Anna Riwkin-Brick, a photographer, did a whole-feminine project when she created the "Children of the world" series books in the fifties and the sixties of the Twenty Century. Walking in her footsteps, I created a trilogy of films about the heroines from the books, more than half a century after she wrote them. It was a long search after the not-so-young heroines. Then came the plague and stopped us all. I started writing a book about my travels worldwide, following the children from the books, about the research I did, other children I found. I watched the raw material on my hard drives from the last decade and took many zoom interviews with more heroes from the books. Suddenly I realized: I have another movie: The fourth in the Trilogy.
