The Lord of the Rings: The Two Towers2002

White Wizard:
You are tracking the footsteps of two young Hobbits.

Aragorn:
Where are they?

White Wizard:
They passed this way, the day before yesterday. They met someone they did not expect. Does that comfort you?

Aragorn:
Who are you? Show yourself! [the White Wizard reveals himself to be Gandalf] It cannot be!

Legolas:
Forgive me. I mistook you for Saruman.

Gandalf:
I am Saruman. Or rather, Saruman as he should have been.

Aragorn:
You fell.

Gandalf:
Through fire and water. From the lowest dungeon to the highest peak, I fought with the Balrog of Morgoth. Until at last, I threw down my enemy and smote his ruin upon the mountainside. Darkness took me. And I strayed out of thought and time. Stars wheeled overhead and everyday was as long as a life-age of the earth. But it was not the end. I felt life in me again. I've been sent back until my task is done.

Aragorn:
Gandalf...

Gandalf:
Gandalf? Yes... that's what they used to call me. Gandalf the Grey. That was my name.

Gimli:
[surprised] Gandalf!

Gandalf:
I am Gandalf the White. And I come back to you now, at the turn of the tide. One stage of your journey is over, another begins. War has come to Rohan. We must ride to Edoras with all speed.
