The Hobbit: The Desolation of Smaug2013

Gandalf:
[he meets Thorin in Bree] I should introduce myself. My name is Gandalf. Gandalf the Grey.

Thorin:
I know who you are.

Gandalf:
Well, now, this is a fine chance. What brings Thorin Oakenshield to Bree?

Thorin:
I received word that my Father had been seen wandering the wilds near Dunland. I went looking, found no sign of him.

Gandalf:
Ah, Thrain...

Thorin:
You're like the others. You think he's dead.

Gandalf:
I was not at the Battle of Moria.

Thorin:
No, but I was.

[flashback to the Battle of Moria, when Azog beheaded Thror]

Thorin:
(voiceover) My grandfather, Thror, was slain.

Thorin:
Father...!

Thrain:
Stay back!

Thorin:
No, I will fight with you!

Thrain:
Azog means to kill us all! One by one, he will destroy the line of Durin! But by my life, he shall not take my son! You will stay here!

Thorin:
(voice-over) My father led a charge towards the Dimrill Gate... he never returned.

[Thrain charges towards Azog with his bodyguards, and Thorin loses sight of him.]

Thorin:
FATHER!

[flashback continues showing Thorin fighting Azog, cutting his hand, and at the end of the battle, Thorin looks upon the pile of dead dwarves]

Thorin:
(voiceover) Thrain is gone, they told me. He is one of the fallen. But at the end of the battle, I searched amongst the slain, down to the last body. My father was not among the dead.

Gandalf:
Thorin, it's been a long time since anything but rumor was heard of Thrain.

Thorin:
He still lives, I am sure of it.

[pause]

Gandalf:
The ring your grandfather wore. One of the seven given to the Dwarf Lords many years ago... What became of it?

Thorin:
He... gave it to my father before they went into battle.

Gandalf:
So Thrain was wearing it when... when he went missing... That's that, then.
