Pre-production is gearing up on the eagerly-awaited Highlander reboot from Chad Stahelski and starring Henry Cavill, and the director has revealed the most challenging aspect of the movie... the sword fights. Stahelski is best known for directing all four of the John Wick movies, starring Keanu Reeves. Using his extensive experience as a stuntman, Stahelski and his team trained Reeves in martial arts, stunt driving, and firearms, so that the actor could perform as much action in camera as possible.
