Well, we'll move out of London as fast as possible!

[last lines] Professor George Edward Challenger:
[watching the destruction from a distance]
My Lost World. Lost forever. Lord John Roxton:
Now we'll never prove anything in London. Professor George Edward Challenger:
Oh, yes, we will. I thought this might help. [reveals a dinosaur egg] Lord John Roxton:
One of the dinosaur eggs. Hardly worth the lives of all those men. But then nor were these. [reveals a handful of diamonds] Jennifer Holmes:
Johnny! How'd you manage those? Lord John Roxton:
No fire monster's big enough to deprive you of a wedding gift. Manuel Gomez:
Well, "Mrs." is still the best title for a girl. David Holmes:
But, uh, don't you want any of them? Lord John Roxton:
Well, I, uh, I kept a few for the rest of us. Jennifer Holmes:
[the egg is dropped and cracks open]
A baby dinosaur! Professor George Edward Challenger:
Ha! Tyrannosaurus rex! Lord John Roxton:
Ha! But will it live, Professor? Will it be all right? Professor George Edward Challenger:
It'll live long enough to grow as big as a house and terrify all London. David Holmes:
Then what'll we do? Professor George Edward Challenger:
Well, we'll move out of London as fast as possible! [all chuckling]
