In a recent interview with Collider, Doctor Who and Guardians of the Galaxy star Karen Gillan reveals that she has a role in the new Star Wars film. Well, rather her hair will have a role. Since the actor had to shave her head for her role as Nebula in the upcoming Guardians (opening this August 1st), her hair was graciously donated to the Star Wars Episode VII production team to create a new character's wig. Gillan calls the process of shaving her head Alien 3 style hysterical, "It's just so funny to think that my hair is made into a wig, next to all these Star Wars monster heads in a warehouse." Read more at the full Collider interview and look forward to a Karen Gillan Hair action figure from Hasbro in 2015.

Star Wars creator George Lucas, actor Mark Hamill, and sound designer Ben Burtt discuss the concept and creation of the lightsaber. George Lucas recalls that Star Wars was influenced by pirate and swashbuckling films of the '40s, which showcased the romantic side of fighting, illustrated in characters like Errol Flynn's Robin Hood.

StarWars.com has released a fantastic bonus feature from one of the 1997 DVD releases on their YouTube page. This 15-minute featurette produced by Gary Leva focuses on the creation and concept behind the iconic lightsaber and is well worth a look. The only thing it leaves out is why the laser emitter only extends to four or five feet and stops mysteriously... and don't tell us "it's the Force."
