Bergman on Bergman (1970)
Context: I know the first film I ever saw — it must have been some time in 1924, when I was six or so... was Black Beauty. About a stallion. I still recall a sequence with fire. It was burning, I remember that vividly. And I remember too how it excited me, and how afterwards we bought the book of Black Beauty and how I learned the chapter on the fire by heart — at that time I still hadn't learned to read.
