George Lucas is putting on a masters course in lightsaber history in a newly uploaded video.

The creator of Star Wars traces the roots of the lightsaber back to the days of knights and heroes while also explaining how he and sound designer Ben Burtt brought the weapons to life for Mark Hamill to use. Lucas and company walk viewers through the development of the filming techniques as well as and the trial-and-error process of making the laser swords look good on screen with tons of behind-the-scenes footage.

If the video looks familiar, it's because it was originally included on the original trilogy Star Wars DVD set.
