You know, I never thought about it until the recent mock-ups - are those "bridges" supposed to be bridges or supports for the inner elevator tube inside the tower shaft? I guess that's the problem with the shaft around the elevator being unmolested by any sort of gantryway looking things in that without anything connecting the inner tube with the outer tower structure, it wouldn't be very stable.

Like I mentioned in an earlier post a few pages back (its funny how ideas you bring up are brought back up again by other posters), it would be kinda cool to see Palps falling down Mola Ram style, though I have no idea how one could do it other than taking the Mola Ram scene or the Gandalf TWO TOWERS entrance scene and modifying them appropriately.

Or we could just leave it as is.. >:)
