When I just 25 Creepiest Lines in Cinema gestolpert bin, but I had to smile, about space 20:

„Look! It’s moving. It’s Alive. It’s Alive…It’s Alive!“ — Dr. Frankenstein (Colin Clive), Frankenstein 1931

Or this quote is still very nice:

„Listen to them. Children of the night. what music they make.“ — Dracula (Bela Lugosi), Dracula 1931

But the original quote from Hellraiser:

„We will tear your soul apart.“ – Pinhead (Doug Bradley), Hellraiser 1987

I had to admit the rare case, that the German translation is better here. What's a lax „We will tear your soul apart“ against the beautiful rough „We are en-Shred Your Soul!“ :)
