The moment every LOTR fan knows in The Two Towers
We told you this was coming, didn’t we? In The Two Towers, Aragorn, Gimli, and Legolas learn about the untimely demise of Merry and Pippin, Aragorn (Vigo Mortensen) kicks the crap out of an Uruk helmet out of despair. He then falls to his knees and howls in anguish and pain, both because of the loss of his hobbit companions and because he broke his toe.
Also, in The Two Towers, Legolas (Orlando Bloom) suffered broken ribs after being unceremoniously thrown off of a horse. Man, there were plenty of injuries to go around, and not even the star actors were safe from harm. We might as well tell you that Vigo also chipped a tooth while shooting a fight scene (also in The Two Towers).
