Smeagol looks back at Sam and smirks evilly as Frodo walks ahead.

Minas Morgul ... once known as Minas Ithil, home of the Witch King.

A sickly blue-green light erupts from the Tower of the Moon.

Leaping up into the sky. Sauron unleashes his hordes for war on Gondor.

Frodo and Sam look shaken as the ground rocks beneath them. Gandalf (voiceover): "The board is set ..."

A Nazgul on a Fell Beast rises into the air above Morgul.

It spreads it's wings ... but is this the Witch King?

Gandalf at Minas Tirith. "The pieces are moving."

A Nazgul swoops as the Rohirrim ride for Minas Tirith - or perhaps they are Ithilien Rangers retreating from Osgiliath.

Several horses and riders are taken out.
