Viggo Mortensen, best known for his roles as Aragorn in Peter Jackson’s The Lord of the Rings film trilogy said in the interview:
“If you don’t make an effort outside of the compounds of your own little life, your own concern; if you don’t make an effort to improve the lot of others, then life for us and for our world is [dying] in terms of The Lord of the Rings. The long defeat, you know: that slow, downward journey to death. Really. There is nothing else.
Each individual on his own free will has a choice to make life more than that fall. And I think that’s at the heart of the book, that’s what it is about. You can and ought to try to make a difference.”
