The camera is the tip of the arrow as it races towards Boromir, who is peering into the Hall from Balin's Tomb in Moria. (We saw this in the first FOTR Trailer)

Out in the open air again, the Fellowship is in a hurry. Probably escaping out of Moria. Notice the arrow in the foreground flying by as Merry looks surprised. (We saw this in the first FOTR Trailer)

The arrow misses the entire Fellowship. Ringer Fan Gnosis suggests, "If you watch the arrow in Quicktime you will note that the arrow is SHOT AT the Orcs - the Elves of Lorien are in front and shoot right past the Fellowship - I think this is the moment they are 'saved' by the Elves."

COMES TO LIFE

Shot from the air as we see frodo reaching for the ring as it drops into his hand.

(CONFIRMED)
The shot of Frodo on the floor with the ring tumbling towards him is in the Prancing Pony in Bree. In this amazing slow-motion shot, the ring "accidentally" lands on the finger of the Hobbit's outstretched hand, after he's fallen from the table. An interesting illustration of the ring's "will."

The Black Rider snuffling for the hobbits in the Shire. It is their first encounter with the rider.
