- Mr. George Devlin: [opening narration] It has been said that many men have found their way through the valley of violence to the palace of wisdom. But if all men must learn wisdom tomorrow from violence today, then who can expect there will be a tomorrow?
- Devlin: My God, Henry, what you've done... it's satanic!
- Mr. Hyde: If you kill me, you'll be killing Henry Jekyll!
- Devlin: You don't understand, do you? Jekyll deserves to die - he's the one who's responsible, not you.
- Dr. Lanyon: Gentlemen, have you ever contemplated the horror of eternal damnation?
- Dr. Wright: [chuckling] Well, not in terms of myself, no!
- Dr. Lanyon: [very serious] Then do contemplate it - in terms of your friend Henry Jekyll.
