Directed by Ridley Scott. With Keith Carradine, Harvey Keitel, Albert Finney, Edward Fox. A duel between two feuding Napoleonic officers eventually evolves into a decades-long series of duels, after each bout - for various reasons - ends unresolved.
The Duellists is one of my all time favourite movies. Since I can remember, I have had a very deep attraction to the Napoleonic period and this movie captures the notion of honour in a very unique way.
