Celia Imrie is a wonderful British actress, very gifted in comic roles.
In Nanny McPhee she plays the role of Mrs Quickly, the betrothed to Mr. Brown.
Unfortunately, great aunt Adelaide (Angela Lansbury) issues an ultimatum to her nephew: she will stop giving the family the allowance which they depend on unless Mr Brown remarries within the month. If he refuses, the family will lose everything, so Mr. Brown is forced to marry the exuberant lady played by Celia Imrie.
She is fantastic as usual and she looks visually appealing thanks to her colorful and flashy costumes and her messy yellow hair and her heavy makeup.
Great performance, really funny.
I love Emma Thompson
