(Boromir runs to lock the door. Arrows are shot and he is almost hit in the face. Aragorn drops his torch and yells to the Hobbits)

Aragorn: Get back! Stay close to Gandalf!

(Aragorn runs to Boromir and closes the doors. A troll can be heard from outside)

Boromir: They have a cave-troll.

(Legolas tosses spears and axes to Boromir and Aragorn to help blockade the door. The Fellowship draws out their weapons and Gimli leaps atop Balin's tomb and brandishes his axe)

Gimli: Aarghhh!! Let them come! There is one dwarf yet in Moria that still draws breath!

(Orcs begin breaking the door down. Legolas and Aragorn shoot at them through the holes in the door. The orcs finally manage through the doors and the battle begins. Suddenly, a cave troll smashes trough the rest of the doors. Legolas shoots an arrow at him, but he just growls. Sam looks up just to see the troll swinging his mace down at him and he throws himself under the troll's legs just in time. Legolas kills orcs on a ledge on one wall. The troll swings his chain at Legolas, who avoids it several times until the troll wraps it around a pillar by accident. Legolas stamps the chain tight and then runs along it onto the troll's head. He shoots the troll in the back of it's head and then jumps off. The battle goes on and Sam hits an orc with his frying pan)

Sam: I think I'm getting the hang of this.

Aragorn: Frodo!

(The troll continues to seek Frodo who tries to hide behind a pillar. After some hide-and-seek, the troll finds him and grabs him. Frodo falls on his back into a corner. The troll lifts him, and he hangs dangling from the troll's hand.)

Frodo: Aragorn! Aragorn!

(Frodo cuts the troll's hand with Sting. The troll drops Frodo to the ground and growls)

Aragorn: Frodo!

(Aragorn grabs a spear from the floor and stabs the troll in the chest. The troll hits Aragorn and sends him flying across the room. He collapses onto the floor. Frodo crawls after him and tries to rouse him, but Aragorn is too stunned to move. Merry and Pippin throw rocks at the troll to no avail. Frodo begins to run, but the troll blocks his way with a spear, throwing him back into the corner. The troll stabs Frodo in the chest. Frodo falls to the floor. Merry and Pippin yell.)

Sam: Frodo? Frodo!

(Merry and Pippin leap onto the troll's head and start stabbing him. The troll finally grabs Merry, swinging him around and throws him to the ground. The Fellowship redoubles its efforts against Orcs and troll in furry. Gandalf and Gimli take turns stabbing at the troll and dodging out of range. Legolas takes aim. With Pippin stabbing the troll one more time on the head, the troll opens its mouth. Legolas shoots and arrow into it's neck. The troll moans then collapses to the ground. Pippin is thrown against the floor and is knocked out. There is a moment of silence. All Orcs are dead or has fled. Aragorn awakens and crawls over to Frodo.)

Aragorn: Oh no!

(He turns Frodo over. Frodo gasps for breath. Sam startles and runs over to them)

Sam: He's alive!

Frodo: I'm all right. I'm not hurt.

Aragorn: You should be dead! That spear would have skewered a wild boar.

Gandalf: I think there's more to this hobbit than meets the eye.

(Frodo reveals his Mithril shirt. Sam touches it in wonder.)

Gimli: Mithril! You are full of surprises Master Baggins.

(Orcs are once again heard down the hall)

Gandalf: To the bridge of Khazad-Dûm!

(The Fellowship runs out the back door of the chamber, pursued by a large army of orcs. Other orcs spring out from the floor or crawl down from the ceiling and down the pillars like spiders. They surround the Fellowship, who have drawn their weapons. Just then a fiery light appears at the end of a hall followed by a thunderous growl. The orcs, scared, flee panicking in all directions. The Fellowships stares towards the light.)

Boromir: What is this new devilry?

Gandalf: A Balrog. A demon of the ancient world. This foe is beyond any of you. Run! Quickly!
