Back in the late 1980s, Meryl Streep mentioned in a newspaper article that she was interested in doing a film version on Broadway hit, EVITA. But Hollywood decided to go with a non-actress instead.
Many years ago, I first heard of Florence Foster Jenkins when someone was talking about Mrs. Miller, a popular and frequent novelty act guest on the Merv Griffin syndicated talk show. She was not as off-key as Jenkins but she did make one think of those Margaret Dumont characters Groucho Marx constantly teased. And Mrs. Miller recorded albums.
I feel that Meryl Streep made a similar and calculated Irene Dunne-like turn when she made SHE-DEVIL in 1999 to break up the dramas. She needed to play kitchen-sink women. She needed to play someone who seemed accessible and of common clay. She needed to make us laugh. Then came her comedies POSTCARDS FROM THE EDGE (1990), DEFENDING YOUR LIFE (1991) and DEATH BECOMES HER (1992). In two of those, she sings. She's at her funniest while singing in FLORENCE FOSTER JENKINS.
