Space Mutiny (1988)
Lea Jansen: [Lea and Ryder quarrel after surviving a shootout in the Southern Sun's engine room] ... I thought you'd be happy to see me.
Ryder: Of course I am. But that's not the issue. Your father should have stopped you.
Lea Jansen: My father stopped interfering with my life when I was fifteen years old.
Ryder: I have every respect for your father. He's a good man. I just wish he could control you as well as he does this ship.
Lea Jansen: Control me? If I hadn't saved you in that engine room...
Ryder: Oh come on, I could have gotten out of that situation, no problem.
Lea Jansen: Well that's gratitude.
Ryder: Why did you do it?
Lea Jansen: Because... oh never mind. You really are stubborn.
Pirates: Surrender, or be blown to astro-dust!
Kalgan: It's not unlike ancient dental equipment on Earth - not that you'd know anything about that!
Chief Engineer: We've been in space too long. Let us land the ship! We can do it, we have the power.
MacPhearson: It's true, we have the power to do this. But this would directly oppose the law of the universe, the law of the galaxy.
Chief Engineer: Forget the law.
Engineer Parsons: No! The law must be upheld, we cannot break it.
MacPhearson: Gentlemen, it seems that we are not all in agreement. Engineer Parsons seems content to spend his remaining years on the Southern Sun.
Chief Engineer: Then let him do so. Alone!
Engineer Parsons: This is mutiny, this is treason, which I warn you I must report!
MacPhearson: Will you allow him to spoil your ambitions for a greater future?
Chief Engineer: We'll not allow that, no!
[the other engineers grab Parsons and beat him up, then MacPhearson uses his walking stick to stab Parsons through the heart, killing him]
MacPhearson: Are there any other of you that wish to confuse freedom with treason?
