Gandalf:(v.o.) You cannot pass!
Frodo:(v.o) Gandalf!
Gandalf:(v.o) I am a servant of the secret fire, wielder of the flame of Anor! Go back to the shadow. Dark fire will not avail you, flame of Udun!
(Zooms into Khazad-dum, Gandalf is confronting the Balrog)
Gandalf: YOU SHALL NOT PASS!
(Gandalf strikes his staff down and causes the bridge to crack. The Balrog falls, and as he falls he snaps his whip which reaches up and grabs Gandalf by his ankle. Gandalf is pulled back, causing Glamdring and his staff to fall after the Balrog and he clings to the ledge by his fingertips. Frodo starts to run to Gandalf, but Boromir grabs him and holds him back.)
Boromir: No! No!
Frodo: Gandalf!
(Gandalf is clinging desperately to the ledge, his fingers groping for a better hold)
Gandalf: Fly, you fools!
Frodo: NO!!!!
