The orcs rush the chamber!

The lead Moria Orc charges at Boromir.

Boromir puts his shield up to block the attack.

The orc screams in Boromir's face.

Boromir deflects the attack with his shield and swings...

he slices into the orc with one ...

mighty stroke.

The entire door and frame shatter...

as the Cave Troll wrecks into the room.

The Cave Troll, wielding a large hammer, looks for his first victim

Sam looks up in horror as he faces the Troll.

The troll takes a mighty swing...

as Sam races to scrabble between its legs.

The hammer pounds into the ground just behind Sam as he narrowly escapes.

Cut to a shot from earlier on, as the Fellowship dares to cross Caradhras. They're on an icy ledge above a great gulf of emptiness.

Zoom out of the above shot.

Voiceover (Aragorn): "We must turn back."

Aragorn is shielding the Hobbits from the elements.

Voiceover (Gandalf): "No!"

Many fans have written in with a little detail that makes all the difference. Notice how the entire Fellowship is knee deep in snow, whil Legolas casually glids on top? Very cool!
