Found this while poking around reddit this morning:
Note: the tiny, glowing figure in front of Ungoliant is Morgoth from the first entry. The tiny glowing object in front of Ancalagon? A ship.
Note 2: Gothmog actually died of the stab wound (when Ecthelion “headbutted” Gothmog, he actually drove the spike on his helm into his chest) or just possibly by drowning. Balrogs aren’t actually injured when their fires are put out (which requires full immersion. Rain won’t do it.).
Note 3: The lumpy-faced guy at the Pelennor Fields was named for the original Gothmog. Either he was just that badass, or Sauron just couldn’t stop imitating Morgoth’s style.
