Looks like George Lucas was at the Detours panel at Celebration 6!
This is an amazing appearance by George in that he comes off like a bit of a jerk
1. He makes jokes about Seth Greene's and the other writer's height.
2. He makes jokes that he basically can't stand them and can only stay around them for a short time.
3. He makes a racist comment. All the writers are taking photos of their experience onstage. George jokes about this and says "The writers are all tourists" and "Our writers meetings take place in Japan!" So essentially hes saying that japanese people are known for taking pictures everywhere. Nice stereotype.
4. The actor who voices Obi Wan Kenobi for the clone wars shows up onstage and introduces himself to George. Apparently hes never met him!
This somewhat hostile attitude from George definitely makes me believe the story of the fans who asked him about releasing the untouched OT and him telling them to grow up. The guy we see on stage in this clip would definitely do that.
Another thing I've observed about Detours is that it takes place between Ep. 3 and ep. 4. But the main characters are pretty much all OT characters. Why didn't George make a show making fun of the prequel characters? Oh yeah because he hates the OT and doesn't care.
I'm sure he totally comes off like a jerk in this clip if that's what you're looking to see. All I saw was George joking around casually with the writers of the show. I don't know about ya'll, but I make short jokes all the time at my friends expenses, and they usually come back pretty quickly with something about my weight. It's all banter.
Yes, the thing about the Japanese taking pictures is indeed a stereotype. It's a very well known stereotype, and like all stereotypes, it's based around some degree of truth. What's your point? The guys were running around the stage taking pictures left and right and he made a joke about it.
And as far as the James Arnold Taylor thing goes. I'm pretty sure that was a joke based on the fact that he fake fainted. And even if they had never meet, would that really by that difficult to believe. Lucas works with the writers of the show. Dave Filoni directs them. It doesn't make him an ass for not having ever meet him.
He is making fun of the prequel characters. Dexter Jester, Padme, Palpatine, Obi Wan, Cad Bane, Qui Gon, Anakin, Jar Jar Binks...prequels. Setting the show between III and IV allows them to make fun of both sides of the series as much as they can. You seem to be suggesting the that prequels are the only part of the series that should be made fun of and the originals are therefore some how holy and exempt like the face of Muhammad or something. "Oh, George Lucas is making fun of the original trilogy because he hate the original trilogy while I completely ignore the obvious jabs he just made at the prequels."
