Gandalf says something along the lines of : "tell me, when did Saruman the wise abandon reason for madness?"

I can't rightly remember, but I think that's pretty close.

That would be correct

Yay! My turn!

Bilbo frightening some little hobbitses at his party. :D

That's it indeed. Gold Star for Dimturiel!

Thank you very much!

Frodo to Boromir, possibly...

Aye, you are right.

"That is not..."
have at it.

Gandalf says something like...

"So do all who live to see such times, but that is not for them to decide."

to Frodo in Moria

Yup, all your's gralin

Pretty easy, but I haven't seen the movie in some time and I don't remember very many more lines.

Gimli at the Council of Elrond "I will be dead before I see the Ring in the hands of an elf"

Very good. Your turn.

Okie dokie, this will easy because I can't think of a harder one.
"...little more caution..."

Strider to Frodo in the Prancing Pony.

Ja, take it away, Dimturiel.

Have fun!:)

Aragorn to Boromir alongside the River Anduin?

"I would not lead the Ring within a hundreds leagues of your city!"

Correct!

Okay:

Stab in the dark...

Gollum to Frodo on Mount Doom...

"Thought it could get away? Did he Precios? (sp!!) Not this time! Not this time"

I can almost hear Andy Sirkis say it even if it is wrong.

Or is it Frodo to Sam at the end when he's paddling his little Hobbit heart out to get across the river?

I'd forgotten about that one, Kitanna.

But I one I'm looking for is somewhere in the EE, I believe...

The "EE"? What is that? If it gives away the answer don't tell me...

I can think of that line in the LOTR game The Third Age, but that's definatly not it...

EE=Extended Edition :)

Another stab in the dark...

Boromir to Frodo when he's "posessed"?

Nope, take another guess. :)

Need a[nother] hint?

To my utter dismay yes I do...

Sorry about the delay...

Hint: It's said in the second half (or last third?) of the movie...after the Fellowship has already left Lothlorien.

Frodo to Sam on the banks of Anduin.

Yep. You're up.

Good luck!

Gandalf to Frodo

"Let the Ring Bearer Decide..."

"We will go into the mines..."

"So be it"

Nope, that's not what I am looking for.

I have no luck... *pouts*

And to think I used to be able to recite the entire movie script by heart!
Sorry continue (says to self: 'Bad Ellewen. Bad!)

Is it Saruman to Gandalf?

No, I'm afraid it isn't.

Ok, I think I have it now. Elrond at the Council?

Yes, that's the one.
