From The Making of Casablanca: Bogart, Bergman, and World War II
Of the stars, Bergman had the more difficult job. Bogart had only to play a man in love. Foreshadowing without giving away too much, Bergman had to let the audience know that love wasn’t enough.
ILSA. And I hate this war so much. Oh, it’s a crazy world. Anything can happen. If you shouldn’t get away, I mean, if something should happen to keep us apart. Wherever they put you and wherever I’ll be, I want you to know that I — Kiss me! Kiss me as though it were the last time.
And Bergman had to hold the audience even when she was saying dialogue that was so richly romantic that it was almost a parody, including, “Was that cannon fire? Or was it my heart pounding?”
Her voice and her face could make almost anything believable. In 1947, several top sound men agreed that Bergman had the sexiest voice of any actress. “The middle register of her voice is rich and vibrant, which gives it a wonderfully disturbing quality,” said Francis Scheid. “It’s sexy in a refined, high-minded way.” “The face is quite amazing,” says Pauline Kael. “I think she had a physical awkwardness on the stage and in her early films, but I think somehow that the beauty of her face obviated it. Even in Casablanca, her physical movements are not very expressive. But you didn’t really care.”
