The Hobbit: An Unexpected Journey2012

Galadriel:
The dragon has long been on your mind.

Gandalf:
This is true, my lady. Smaug owes allegiance to no one, but if he should side with the Enemy... A dragon could be used to terrible effect.

Saruman:
What enemy? Gandalf, the Enemy is defeated. Sauron is vanquished. He can never regain his full strength.

Elrond:
Gandalf, for four hundred years, we have lived in peace - a hard-won, watchful peace.

Gandalf:
Are we, are we at peace? Trolls have come down from the mountains, they are raiding villages, destroying farms. Orcs have attacked us on the road!

Elrond:
Hardly a prelude to war.

Saruman:
Always you must meddle, looking for trouble when none exist...

Galadriel:
Let him speak.

Gandalf:
There is something at work beyond the evil of Smaug. Something far more powerful. We could remain blind to it but it will not be ignoring us, that I can promise you. A sickness lies over the Greenwood. The Woodsmen who live there now call it Mirkwood and, uh, they say...

Saruman:
Well, don't stop now. Tell us what the Woodsmen say.

Gandalf:
They speak of a Necromancer living in Dol Guldur, a sorcerer who could summon the dead.

Saruman:
That's absurd. No such power exists in this world. This "Necromancer" is nothing more than a mortal man, a conjurer dabbling in black magic.

Gandalf:
And so I thought too, but Radagast had seen...

Saruman:
Radagast? Do not speak to me of Radagast the Brown. He is a foolish fellow.

Gandalf:
Well, he's odd, I'll grant you. He lives a solitary life...

Saruman:
It's not that. It's his excessive consumption of mushrooms! They've addled his brain and yellowed his teeth!
