Holy technicolor!! While “Black Narcissus” struck me as obnoxious, this is utterly charming. There’s something about a “backstage story.” Can an artist be true to their craft, yet still have a life? Not according to this movie. The ballet-break in here puts “American in Paris” to shame. Hot stuff, heartbreaking and Moira Shearer, who died 20 days ago at age 80, was a stone cold fox.
