Full-disclosure: I'm totally unfamiliar with the source novel, Pride and Prejudice and Zombies by Seth Grahame-Smith and published by Quirk Books because reading is for suckers. Seriously, who has time for that? Also, books seem to be filled with words, and movies are filled with pictures. Movies are just easier.
Darcy, Colonel Darcy, clad in a leather trench coat because it's the 19th century, carries around a tiny bottle containing carrion flies to help weed out the zombies from the regular folk because that's often difficult amongst the aristocracy. Then he kills them. Meanwhile, Elizabeth Bennet concerns herself with corseting, frowning, and concealing knives in her garters. A mysterious plague rages within the walled city of London, and the stricken are beginning to find their way into the upper classes' country estates.
Featuring good choreography, PG13-level gore, xenophobia, classicism, social intrigue, and haughty dialogue during martial arts which creates a humorous juxtaposition, Pride and Prejudice and Zombies is a well-mannered period drama punctuated by zombies. I particularly enjoyed the well constructed scene of martial arts and sexual tension between Darcy and Elizabeth in a wood-paneled drawing room, the scene in the potter's field where the hands of rotting corpses reach out from beneath the wet earth, and the unsettling scene as an aristocrat offers cake to the bourgeoisie to fuel the rise to revolution. Wait, was that this movie, or the French Revolution? It might have been both.
Anyway, Pride and Prejudice and Zombies was cute and funny, but seemed a bit overlong due to all the romance.
