Miss Pettigrew (Frances McDormand) is a penniless nanny, currently out of a job. Although she has worked for a placement agency in the past, they give her the cold shoulder this time, mostly because her last three stints as a nanny, with impossible children, fared badly. Absolutely desperate for work, Miss Pettigrew hears of a position as a social secretary as she is walking out the agency's door. Making a beeline to the appropriate home, she encounters the young starlet, Delysia La Fosse (Amy Adams) who asked for her services. But, what doings! Delysia has had a male guest, overnight, who is not the man who owns the flat where she is currently bunking! The interloper must be ushered out before Mr. Moneybags returns or Delysia will be in a heap of trouble. Not missing a beat, Miss Pettigrew gets the situation under control with her innate wisdom. Delysia is grateful. But, the day is only getting started. There is a third man in Delysia's life and the young beauty is juggling suitors in a quest to become a bonafide star of the screen. Not only that, Delysia whisks Miss Pettigrew off to a fashion show and salon, where the new social secretary gets a makeover and meets a rich, handsome man (Ciaran Hinds) with eyes for HER. Is it possible to go from rags to riches in twenty four hours? Definitely, maybe! This is a lovely film with a great plot and a terrific cast. Adams is engaging as the beautiful but mixed-up starlet while Hinds is marvelous as the man who rediscovers what is important in life. The rest of the players are also wonderful, with a word of mention extended to Shirley Henderson for her nice turn as a conniving, inconvenient woman. But, really, this is McDormand's film, as she is the heart and soul of the picture and deservedly so, for her performance is absolutely enchanting and touching. Needless to say, the sets and costumes from the late 1930's are grand and so are the film's art direction and photography. Congratulations are hereby given to the fine, fine script and story, as well. Do you want to experience movie bliss? Then, don't miss Miss Pettigrew Lives for a Day, as your day will be as bright as newly minted penny, after a viewing.
