Orcs on the prowl, or rampage? Possibly Uruk-hai, since it is daylight. This could mean that these are orcs involved in fighting at Helms Deep, or in capturing Pippin and Merry. Mountainous region, very likely Uruk-hai of Saruman.

Same shot, with a new face. Angry Orcs!

Nazgul in pursuit of the Ring emerge from the mist...

Shock! Frodo Baggins of the Shire, played by Elijah Wood, stares in horror. At Weathertop his hobbit companions stand guard in a circle behind him

One ring to bring them all

Legolas Greenleaf leaps through the air!
OR could this be Arwen carrying Frodo to safety replacing Glorfindel as they race to Rivendell?? OR Could this be Gandalf on shadowfax?

Orlando Bloom looks like he’s resorting to knifework or pulling an arrow here at Helms Deep.
