As Liv Ullmann said in The Guardian:

Woody Allen came to get me, and he was so excited, he was shivering and talking, talking. Anyway, Ingmar opened the door and said welcome. That’s all he said. And the two of them looked at each other. Two geniuses met. We sat down at the table — and this is the honest to God truth, Ingrid was sitting there, I was sitting there, Ingmar there, and Woody Allen there — and they did not talk. They just looked at each other, almost lovingly.
