- [as the submarine enters the brain]
- Dr. Duval: Yet all the suns that light the corridors of the universe shine dim before the blazing of a single thought...
- Grant: ...proclaiming in incandescent glory the myriad mind of Man.
- Dr. Michaels: Very poetic, gentlemen. Let me know when we pass the soul.
- Dr. Duval: The soul? The finite mind cannot comprehend infinity, and the soul, which comes from God, is infinite.
- Dr. Michaels: Yes, but our time isn't.
- Grant: What happened?
- Capt. Bill Owens: Dr. Michaels... went berserk.
- Grant: Berserk nothing!
- Dr. Michaels: Grant, help! Get me out!
- Grant: [hands SCUBA gear to Owens] Get this on, quick. If a window blows, we'll lose this air lock.
- Dr. Michaels: Grant, help. I'm trapped. Help me!
- [Grant struggles to free Michaels as he grows increasingly agitated]
- Dr. Michaels: Can't get my... can't get my hands out. Get me out of here. My... my hands are trapped. Can't move... can't move my hands. I can't move my ha... move my hands. Can't move my hands! Get my out! Get me out of here!

- Dr. Michaels: It throws down quite a barrage. Over 40 million beats in a year.
- Dr. Duval: And every beat separates a man from eternity.
