This 15-minute Star Wars featurette won't tell you how to make an actual lightsaber, but it will explain how director George Lucas and his team created the first lightsabers for A New Hope, and Mark Hamill tells what it was like to wield them.

You may recall this video from the original Star Wars trilogy DVD boxset, but it's definitely worth a re-watch now that it's available online. My only regret is that this video wasn't titled "Everything You Wanted To Know About Lightsabers (But Were Too Afraid Of Getting Your Hand Or Arm Cut Off To Ask)."
