Quote from : The Hobbit: The Desolation of Smaug Movie

Gandalf: Oh, it's you.
Radagast the Brown: Why am I here, Gandalf?
Gandalf: Trust me, Radagast. I would not have called you here without good reason.
Radagast the Brown: [Radagast removes his hat to allow the birds to hide underneath] This is not a nice place to meet.
Gandalf: No, it is not.
[They exit the tomb]
Radagast the Brown: These are dark spells, Gandalf. Old, and full of hate. Who's buried here?
Gandalf: If he had a name, it's long since been lost. He would have been known only as a servant of evil. One of a number.
[He shines his staff into the chasm, revealing the doors of the tombs, all with the bars broken open]
Gandalf: One of nine.
