Bob Anderson, one of the world’s top sword masters and fencing choreographer for such movies as Lord of the Rings, Highlander, Star Wars, Pirates of the Caribbean, and The Princess Bride, has died, according to TheOneRing. He was 89.

Anderson, who was born on September 15, 1922 in Hampshire, England, taught many actors fencing techniques and was a stunt double for David Prowse’s Darth Vader in The Empire Strikes Back and Return of the Jedi. He actually also trained actor Errol Flynn, who is known for his iconic swashbuckling roles.

According to TheLordOfTheRings.net, after the master swordsman read J.R.R. Tolkien’s Lord of the Rings books, he “developed sparring methods based on Tolkien’s descriptions of each culture.”
