Lansen confronting the Grand Inquisitor

This scene is one of the most powerful moments in the film. Lansen encouraging the Spaniards to come with them and escape and the Grand Inquisitor trying to nip it in the bud, and then they have this dialogue:

Lansen: We're getting out. Now we can noisily, or we can go quietly. The choice is up to you.
Grand Inquistor: [unimpressed] Where are you going? You're trapped here like the rest of us. There's no escape.
Lansen: How do you know? Have you ever tried?
Grand Inquistor: Our ancestors tried.
Lansen: I'm not talking about them, I'm talking about you.
Grand Inquistor: It's God's will!
Lansen: [angrily] It's your will, because you want it this way! You do it in the name of God through this child here because you haven't got the guts to do your own dirty work!
Grand Inquistor: [changing the subject] You speak bravely of escaping. How are you going to do it?
Lansen: I don't know, but we'll try.
Grand Inquistor: You will fail!
Lansen: Then we'll go on trying, and the day we stop trying we stop living!

Lansen is the ultimate optimist, whereas his foe is the ultimate defeatist (mostly because he likes controlling his little microcosm of Spanish society). This debate of ought they accept their fate and stay, or should they throw caution to the wind and die trying to get away, ALMOST elevates this bizarre little movie above being simply another B-movie.

Sadly, one scene of dialogue, even powerful dialogue, can't save this insane movie. I just wanted to point out how much I like that scene.
