Don't get this confused with the Def Jux dj RJD2. I'm referring to Ryan vs. Dorkman 2, so there should be no confusion. Type in 'light saber' on Ye Olde YouTube, you'll get close to 10,000 matches. And there's a good chance these arch-nemeses (is that right?) will appear at the top of the results.
Arguably the epitome of Star Wars fan film light saber battles, my son and I had the good fortune of viewing the sequel at the end of the NY Comicon, courtesy of the folks of nyjedi.com. RvD2 premiered on the 'tubes' March 1, so the rest of the world can view it in its infinite goodness. Enjoy.
