its a nice theory but there's not 100% proof thats her... if there is can we get a link saying that she was in the scene and then altered at the last moment.
maybe its just an elv, nothing more, nothing less.
Not trying to disprove you, but I don't see any proof...the pictures are too blurry and it could really be anyone.
i noticed something else from ttt, at the beginning, when gandalf goes "fly you fools" of course hes looking right at them, after frodo goes nooooooo, and gandalf falls, look to the right...you can see frodo and that other guy (cant think of his name) and you can see gandalf..falling ON THE LEFT...far away! ive noticed it tons of times...first hes close to be right in front of them, and then far away and it looks as if frodo and the other guy are in a different spot
do you guys get what im saying? its very hard to explain but if you go back and look you can see what i mean
hehe
