From Twilight Samurai
Twilight: Zenemon Yogo, by order of the clan I come for your life. Draw your sword, please.
Zenemon: Have a drink. I know you're all keyed up, but I'm going to run.
Twilight: Run?
Zenemon: Yep. I want you to let me get away. If you please.
Twilight: I didn't expect that from the clan's best one-sword man. My orders are to kill you. I can't let you escape.
Zenemon: Don't be so impatient, you can kill me at anytime. I'd like to talk to you. Have a seat. It's a nice day. Sit down.
Twilight: Even if you escaped, where would you go?
Zenemon: Over that mountain and I'm out of the clan's domain. There are masterless samurai everywhere. I can lose myself in them. Go to Kyoto, to Edo...If I do that for a few years, the world will have changed. The samurai's day is done.
Twilight: This isn't the time for that talk. Pick up your sword, please. I am under orders from the clan to...
Zenemon: Like Hell. You're the clan's errand boy out to claim a reward. Have drink. I was an errand boy, too.
This scene goes on much longer than the text I quoted. It reflects on the dominant themes of the film (the unsustainable wages peasants and low-samurai make, illness in Twilight's family, his desperation) in a way that ties everything the viewer has seen together without being forced--this is just the outcome of a broken system, with two men put into bad positions by that system. It ends with a brilliant lead into their fight:
Twilight: I was desperate so I finally sold my sword. It was a fine sword I'd inherited from my father. But I figured, the age of the sword was over. I'm afraid this is just bamboo.
Zenemon: You're going to kill me with a bamboo sword?
Twilight: No! I learned short-sword from Toda-sensei! I meant to fight with that.
Zenemon: Short-sword? You mean to kill me with some kind of cheap trick? You're not taking me seriously, are you?
Twilight: Wait!
Zenemon: I won't have it!
Which now transitions to one of the best fight scenes, and
the best sword fighting scene, in film. But dealt with in the tense portions during their conversation are what I mentioned above, as well as the failure of samurai with more liberal outlooks on their lifestyle (and an understanding that it can't continue!) still falling prey to the rigidity of their class system (short-style = disrespect = sorry bro, we gotta do this). It really, really, really, really plays out better visually, so watch it!
Here's a handy Youtube link. Trust me, it's a scene that is hard to capture through text, and the dialogue itself is much better with its staging present. A great, great movie.
