Unknown World (1951)

Dr. James Paxton: Nature doesn't influence Man! Man influences Nature! One strong man can change Nature!
Wright Thompson: Oh, you're wrong, Dr. Paxton. It isn't one man, it's many men working together.
[Looking at Dr. Joan Lindsey]
Wright Thompson: Right, teacher?
Dr. James Paxton: Men together are no more than sheep! One man standing alone leads the way, and the sheep follow!

Dr. Jeremiah Morley: I believe that humanity can escape annihilation, can find a temporary haven, a promise of hope that, come what may, life can be sustained deep within the Earth itself. Far below the Earth we shall seek a natural, a geologic shelter. We have a team ready for the effort. All we lack are funds.

Dr. Jeremiah Morley: Go back to what? To a world bent on self destruction? We can live the rest of our lives here in peace.
Dr. Joan Lindsey: Morley, you're wrong! This isn't peace! This is a resting place for the dead!

Both the mountains mentioned, Mt Lefat and Mt Neleh, are fictional.
