- Alec McEwan: Where are we?
- [a caveman grunts to get them on the move]
- Professor Oliver Lindenbrook: We are in a prehistoric caveman village. I calculate that we are a few hundred miles below the sands of the Arabian desert.
- Alec McEwan: How do you figure that?
- Professor Oliver Lindenbrook: Look at the walls of this canyon. They're covered with the fill of crude oil. This is the base of the greatest oil vein in the Earth.
- Alec McEwan: Boy, if we could rig a pipeline down here, we'd be rich!
- Professor Oliver Lindenbrook: If we can't figure a way out of here, we'll be dead.
- Professor Oliver Lindenbrook: It seems we are indebted to the cavemen.
- Cindy Lindenbrook: Why is that, Uncle Oliver?
- Professor Oliver Lindenbrook: They chased us in the right direction.
