The clip Waldman and Frankenstein discuss monster from Frankenstein (1931) with Colin Clive, Edward Van Sloan
Come and sit down, Doctor.
You must be patient.
Do you expect perfection at once?
This creature of yours should be kept under guard.
Mark my words, he will prove dangerous.
Poor old Waldman.
Have you never wanted to do anything that was dangerous?
Where should we be if nobody tried to find out what lies beyond?
Have you never wanted to look beyond the clouds and the stars?
Or to know what causes the trees to bud?
And what changes the darkness into light?
But if you talk like that... people call you crazy.
Well, if I could discover just one of these things -
what eternity is, for example -
I wouldn't care if they did think I was crazy.
You're young, my friend. Your success has intoxicated you.
Wake up and look facts in the face!
Here we have a fiend whose brain...
Whose brain must be given time to develop.
It's a perfectly good brain, Doctor.
Well, you ought to know. It came from your own laboratory.
The brain that was stolen from my laboratory was a criminal brain.
Oh, well. After all, it's only a piece of dead tissue.
Only evil can come of it.
Your health will be ruined if you persist in this madness.
I'm astonishingly sane, Doctor.
You have created a monster and it will destroy you.
I believe in this monster, as you call it.
