Visible crew/equipment: After starting their four day journey through the long dark of Moria, a few shots later Gandalf pulls on his hat brim, and just as he walks (with Legolas close behind) to his left (towards the viewer's right), up some stairs, the black electrical cable leading from the staff to under the robe's left sleeve is visible.
Visible crew/equipment: When Saruman points both staffs at Gandalf, he says, "I gave you the chance of aiding me willingly, but you have elected the way of pain!" as Gandalf spins round on the floor, with his left leg raised in the air. As he spins, there is a bulge at his side and the apparatus with the wire, around his left ankle, is perfectly visible.
Visible crew/equipment: After Frodo looks into the mirror and sees the destruction of the Shire, Galadriel is seen riding in the swan boat across the river. Look in the background, on the left bank, a man can been seen sitting there, very faintly. As the scene progresses this crew member can be seen looking back and forth.
