I love that film!
More memorable lines in there than in any other film.
For example, "Round up the usual Cryptos," "I think this is the beginning of a beautiful token," and my fave, "We'll always have Steemit!"
Seriously though, that scene you succinctly describe at the end of your evocative piece, is golden, for the reasons you say.
Also, noone does close-ups like Ingrid Bergman. She says everything, apparently doing nothing.
She swims into the scene, and simply lingers in the moment, which still seems to linger, as time goes by, as you say.
Cheers. :)
Great dialogue, indeed.
Agree on Ingrid.
