Dolores Gray was a dynamic performer
Delores Gray, was a brilliant performer, just watch her in "Kismet". She never was a house-whole name in the US, but that's because she chose to go to the UK and there she became a well known mega-star. Whatever personal and private reasons she had, she elected to pursue a career in England, it was our loss here in the US. I wonder why she chose that path, I'm sure it's interesting. She could of had a great career here, too, above and beyond that of Broadway, where she excelled. She was just as talented and on an equal par as Merman and Martin. She had her Tony, too.
In "Kismet", watch her move on camera, even when she's not even the primary focus. She just had "it", very classy. And what a voice. She "stole the show" in the movie, "It's Always Fair Weather", which was for the most part, story wise and visually, "dark and dreary" anyway, except for Gray and the other actors who tried very hard.
"Kismet" was an under-rated film in it's time, It's certainly an excellent film, very pretty, too.
