The Lord of the Rings: The Two Towers2002

Sam:
It's a bog! He's lead us into a swamp!

Gollum:
Swamp, yes. Yes. Come master, we will take you on safe path through the mist. I found it, I did. A way through the mashes. Orcs don't use it. Orcs don't know it. They go around, for miles and miles! Come quickly. Soft and swift as shadows, we must be.

Sam:
There are dead things. Dead faces in the water!

Gollum:
All dead. All rotten. Elves, and Men, and Orcses. A great battle long ago... The Dead Marshes. Yes, yes, that is their name! This way. Don't follow the lights. [Sam slips and almost ends up in the water] Careful now! Or Hobbits go down to join the Dead Ones, and light little candles of their own.
