I'm a huge Ingrid Bergman fan, though it's hard to top "Casablanca" for dreamy close-ups of her. David Selznick, who loaned her out to Warner Bros. for that movie, sent a thank you letter to DP Arthur Edeson because he felt that Edeson's lighting of Bergman had raised her marquee value.
Interesting thing is that, like the other famous Swede to arrive in Hollywood, Greta Garbo, when Bergman first started in movies, she was rather blandly pretty. It wasn't until they hit their mid 20's that they started to look distinctively beautiful, plus it wasn't until then that the stylists figured out what to do with them, allow their own unique features to come through. I see that a lot in actresses, they can be somewhat generic in their beauty at 18 or 20, and then they get really interesting as they approach 30.
