40 Little-Known Facts About Aragorn from Lord of the Rings
Viggo Mortensen Used a Real Steel Sword
While most of the actors in the films chose to use rubber blades for safety, Viggo Mortensen decided to throw caution to the wind. He used a steel sword and performed all of his own stunts. That decision likely stemmed from Viggo’s desire to be as in character as possible throughout the filming.
Using a real steel sword allowed him to feel the exhaustion that Aragorn might feel during battle. Of course, it also probably made scenes where the sword was used a little more dangerous. Even so, no price is too high to create a sense of realism in high fantasy.
