A new featurette has revealed how the iconic lightsabers were created for the 'Star Wars' franchise.
The 15-minute video, which was first seen as a special feature on the original Star Wars trilogy's DVD boxset in 2004, shows how production staff planned and choreographed the movies' complex fight sequences, the Verge reported.
The video also features lightsabers' inventor George Lucas, who explains and how he was inspired to include hand-to-hand combat by movie swashbuckling and historical Asian swordplay.
Mark Hamill talks about the sabers' fictional weight change, while sound designer Ben Burtt shares how movie projectors came to influence the swords' distinctive hum in the video.
