4.5 Beautifully Filmed, Well Acted, Slightly Boring. Dirtfish | 13/10/2009 | See all Dirtfish's reviews (475) The Duchess (2008) is a drama about 18th century aristocrat Georgiana, Duchess of Devonshire. Keira Knightley stars with support from Ralph Fiennes, Charlotte Rampling and Dominic Cooper.This movie serves to remind us that Keira Knightley is a very good actress. In this movie she is seductive, charismatic and compelling. Ralph Fiennes is far more restrained but gives a great performance elevating the movie and Knightley.Director Saul Dibb (Bullet Boy) keeps the pace of the movie slow allowing the characters to develop. The cinematography is gorgeous and looks especially lush on blu-ray.The Duchess is a quality piece of filmmaking with some top notch acting. It can be a little dull at times but don't let that put you off. A return to form for Knightley.
