Aragorn: Gandalf.
Gandalf: Lead them on Aragorn. The bridge is near. (Aragorn resists, but Gandalf pushes him away) Do as I say! Swords are no more use here.
(The Fellowship runs down the steep staircase. Half way down, they encounter a gap on the stairs. Legolas leaps forward and lands on the other side. He waves to Gandalf.)
Legolas: Gandalf!
(Gandalf looks back up towards the Hall as they hear a loud growl and stones fall around them. Then he leaps after Legolas. Suddenly, arrows whistle in the air, striking the steps they stand on. Legolas and Aragorn shoot back, killing many orcs)
Boromir: Merry! Pippin!
(He takes Merry and Pippin, one on each side, and leaps forward, landing on the other side)
Aragorn: Sam!
(He throws Sam to the other side and is caught by Boromir. Aragorn reaches to pick up Gimli, but Gimli holds up his hand)
Gimli: Nobody tosses a Dwarf.
(Before Aragorn manages to do anything, Gimli leaps forward but nearly falls back into the chasm. Legolas grabs his beard)
Gimli: Not the beard!
(Some of the stone steps crumble and fall into the fires below. Aragorn pushes Frodo back up the steps and climbs after him. They struggle to their feet and look at the widened gap that separates them from the rest of the Fellowship. The Balrog is heard from the other hall, its fiery light is seen. Stone structures around the mine collapse as it draws near. A huge rock falls from the ceiling and smashes down the steps behind Aragorn and Frodo, creating another gap behind them and weakening the stairs' foundation. The stairs begin to wobble)
Aragorn: Steady! Hold on. Hang on! Lean forward! Steady!
Legolas: Come on! Now!
(Frodo and Aragorn shift their weight forward, tipping the stairs across the divide and slamming onto the steps where their companions are. They leap across to safety, catched by Legolas and Boromir. They continue to run down the stairs as the stone structures collapse behind them)
Gandalf: Over the bridge! Fly!
(The Fellowship crosses the bridge. Gandalf stops halfway over and turns to face the Balrog, who appears out of the fires, growling)
Gandalf: You cannot pass!
Frodo: Gandalf!
(A blazing light radiate from Gandalf's staff, illuminating the entire bridge and it's surroundings)
Gandalf: I am the servant of the secret fire, wielder of the flame of Anor. The dark fire will not avail you! Flame of Udûn!
(The Balrog strikes down on Gandalf with a flaming sword. Gandalf parries the blow with Glamdring, shattering the Balrog's sword)
Gandalf: Go back to the Shadow!
(The Balrog brandishes a flaming whip, lashing it about menacingly)
Gandalf: YOU….SHALL NOT...PASS!!
(Gandalf strikes his staff and sword onto the bridge. The Balrog stops, not knowing what to do. As it steps forward, the bridge collapses under it and the demon falls backward into the chasm, growling. Gandalf, exhausted, leans on his staff and watches the Balrog fall then turns to follow the others. At the last minute, the flaming whip lashes up from the depths and wounds about Gandalf's ankle, dragging him over the edge. He clings onto the bridge but is straining to keep his grip. Frodo rushes forward, but Boromir restrains him.)
Boromir: No! No!
Frodo: Gandaalf!
Gandalf: Fly, you fools!
(Gandalf loses his grip and falls into the abyss)
Frodo: Nooooooo!!!
(Boromir grabs Frodo and runs, heading for the stairs leading to the East Gate)
Boromir: Aragorn!
Frodo: Nooooooo!!!
(Aragorn is shocked. He stares at the bridge in disbelief, unable to move for a few moments. But then Orc arrows start whistling by once again. Dodging, he turns and follows the others up the stairs and out in the light. The Fellowship comes running out of the East Gate of Moria. Everyone is distraught. Sam sits on the ground, bows his head onto his hands and begins to weep. Merry consoles Pippin, who lies crying. Boromir tries to restrain Gimli as the dwarf vents out his rage and sorrow. Legolas wears a look of shock and disbelief. Aragorn stands on a distance from the others, cleaning his sword and re-sheathes it. Then he turns to the others)
