The Lord of the Rings: The Two Towers2002

Gollum:
[Sam has him tethered with the Elven rope] IT BURNS! IT BURNS US! It freezes! Nasty Elves twisted it. TAKE IT OFF US!

Sam:
Quiet, you! [to Frodo] It's hopeless! Every Orc in Mordor's gonna hear this racket! Let's just tie him up and leave him.

Gollum:
NO! That would kill us! Kill us! [groans and writhes on the rocks]

Sam:
It's no more than you deserve!

Frodo:
Maybe he does deserve to die. But now that I see him, I do pity him.

Gollum:
[gets up, trying to be polite] We be nice to them, if they be nice to us. Take it off us! We swears to do what you wants! We swears...

Frodo:
There's no promise you can make that I can trust.

Gollum:
We swears to serve the master of the precious. We'll swear on... on the precious! Gollum, gollum.

Frodo:
The Ring is treacherous. It will hold you to your word.

Gollum:
Yes... on the precious. On the precious.

Sam:
[brief silence] I DON'T BELIEVE YOU! [Gollum tries to flee, but Sam pulls him back by the rope] Get down! I said DOWN!

Frodo:
Sam!

Sam:
He's trying to trick us! If we let him go, he'll throttle us in our sleep!

[Gollum gasps, clutching at the rope around his neck; Frodo approaches him]

Frodo:
You know the way into Mordor?

Gollum:
[afraid] Yes...

Frodo:
You've been there before?

Gollum:
Yes...

Frodo:
[removes the rope] You will lead us to the Black Gate.
