From Dracula vs Frankenstein
DR. BEAUMONT is driving his car when suddenly, COUNT DRACULA appears in the passenger seat.
DR. BEAUMONT - Who are you?
DRACULA - Keep driving, I'll tell you where.
DR. BEAUMONT - Who are you?
DRACULA - I am known as the Count of Darkness, the Lord of the Manor of Corpathia. Turn here.
The car stops, and the FRANKENSTEIN MONSTER is there.
DRACULA - Get out of the car Dr. Beaumont!
So DR. BEAUMONT leaves the car and the MONSTER throttles him.
DRACULA - An old friend, doctor. You'll find that Frankenstein and I have made some improvements. Haha hahahaha!
--------------------------
This film has so many great lines. Here are some more.
DR. FRANKENSTEIN - I am too old, and too sick, to be interested or surprised by anything. But when a man enters my house and casts no reflection on my mirror, and upon his hand wears the unholy crest of Dracula, there is no scientific answer to anything! Now, what is on your mind – Count Dracula!?
and later...
DRACULA - And all those who meddle in the destinies of Frankenstein and Dracula will see an infernal bloodbath the likes of which has never swept the Earth before!
The dwarf Gazbo has some great lines.
GAZBO - You see! You must open your eyes to see things.
And...
GAZBO - I'm just a little man of no use to anyone!
