Middle Earth factoids:
In the Two Towers, the scream as Aragorn falls to his knees after kicking the orc head was real. The actor had been kicking the fake head multiple times & in the last take, used in the movie, he broke his toe. But he stays in character long enough....
John Rhys-Davies who plays the shortest member of the fellowship, Gimli the dwarf, in reality was the tallest of the cast. He also provides the voice of Treebeard.
In Return of the King, the bearded pirate on the receiving end of Legolas arrow, knocked by Gimli, is director Peter Jackson in his third cameo. Stood around him are mainly members of the production crew who wanted to be in the final movie.
In the shot where Sam's arm holding sword Sting appears confronting giant spider Shelob...it's actually Jackson's arm in another 'cameo'.
