Deborah Kerr has always been my favorite actress, even when I was a small child. My father had a crush on her, (approved by mom, of course) and he took me along to every movie she was in, in the 1950's.
Her beauty, grace, acting ability, and screen prescence was unparalleled. Oh, by the way, much of the singing you hear in "The King and I" is actually Kerr's own voice. In fact, the first song, "I Whistle a Happy Tune" is completely sung by Kerr. Marni Nixon helped her with the high notes, and notes that required sustaining and a little more polish. In fact, if you listen closely to "Shall We Dance" you can clearly hear the transfer from Kerr's voice to Nixon's. That was how they managed to make the dubbing so seamless. Kerr would start the song, and Nixon would take over.
There will never be another Deborah Kerr. She was truly, one of a kind.
