 The full sized sword props were designed to appear ignited onscreen, by later creating an "in-camera" glowing effect in post-production.The blade is a three-sided rod which was coated with a Scotchlite retroreflector array, the same sort used for highway signs.A lamp was positioned to the side of the taking camera and reflected towards the subject through 45-degree angled glass so that the sword would appear to glow from the camera's point of view.
