[Tuor of Gondolin]

Gollum disappearing in lava with the Ring:

(Thinks to himself, "How about that. That hack Peter Jackson got something right!'). Then says aloud:

"Let's see that f******* f**** Dobby top this death scene!
Can't wait for my Oscar acceptance spee...agh! It burns us! It burns us, precious. Where's that ***** stunt double?
Oh wait, the fat hobbit's throwing us a rope. Let's grab it.
Agh! It freezes, it bites! Elves twisted it, curse them! Nasty cruel hobbit. It hurts....."

PJ: "Cut! Cut! Gollum. Babe! You're doing improv again. Now let's do the scene over the way I improved, I mean adapted, it.

Gollum: "I cannot work with that man. He just drains me!"
