The Magnetic Monster (trailer, 1953)

Sister, here's tenement. We're witnessing the secret of creation. Mr. Mayor, the city must go down to supply the power we need. And after 11 hours? Up then. Then we'll need the entire power of Boulder Dam to feed it.

We must make preparation to evacuate the city. Looking like creatures from another planet. These two scientists risk their lives to move the new Titanic element to the one place where they might fight it. I'm going to set the machine and leave in time.

So the men. But she doesn't build to take such a load. She'll break up. Dr. Benton. Our only hope is that she'll break that element before she breaks herself. One that stood between the Earth.

Only he dared face the terror of the monstrous thing that had suddenly come alive. A cosmic Frankenstein that threatened to engulf the world and herl it into outer space. Delta Trana, this maximum output, and close the floodgate.

I want you all to leave to reach the surface. The magnetic monster battle its deadliest enemy, the giant Delta Trana. See the last desperate chance they took to check its appalling power. See it, Shepherd, the steel walls of its mammoth prison beneath the sea.
