"The Devil Wears Prada" was fun. Anne Hathaway ("Brokeback Mountain," "The Princess Diaries") is actually the central character. The book on which it is based, was written by a woman who briefly worked for Anna Wintour, who was/is the head of Vogue magazine.
Wintour has always been known as a notoriously vain, evil, demanding, self-centered bitch, now recreated with delicious glee by Meryl Streep "A Prairie Home Companion" and "The Manchurian Candidate"), who obviously got a huge kick out of playing a fictitious, glammed-up version of her.
Hathaway plays the whipping boy/girl who applies for the chronically vacant assistant editor's job simply because she is a journalist and wants a chance to write for "Runway" (a fictitious version of Vogue). Her character has never read the magazine and she is obviously tone-deaf when it comes to haute couture.
We enjoy a competent supporting cast, comprised of Emily Blunt ("The Jane Austen Book Club"), who portrays a fellow sufferer/arch rival; and Stanley Tucci ("Swing Vote"), in the de rigueur role of the gay mentor who provides our heroine with fashion tips, wardrobe and a shoulder to cry on.
This movie makes a point of illustrating how petty and arbitrary Streep's character can be; AND, she never lets up or changes! According to what I see/hear/read, Wintour is exactly like that! Yikes!
