ORLANDO, Fla.--You'd think, with all the resources at his disposal, "Star Wars" creator George Lucas would be pleased, if not all that impressed, to see the flood of life-size and (nearly) fully functional droids that fans of his films have created over the years.

In fact, though, Lucas sees those droids--which were out in force at Celebration V, the huge "Star Wars" fan fest here this week--as a bit of a "tragic" reminder of the struggles he and his team had trying to get their own R2-D2s to work properly back when they were shooting "A New Hope," the first film in the monumentally popular saga, back in the 1970s.

Indeed, Lucas told a capacity crowd of several thousand here Saturday, he labored for eight years trying to get the group of R2-D2s his production had to work with to go in a straight line, and in the end, he said, they had to fashion a sort of fiberglass model, put it on sticks and use wagon wheels to achieve their goal.

"Here, they have the most beautiful R2 units you can possibly imagine," Lucas said, adding, to a huge cheer, "They're magnificent. If only I could make another 'Star Wars.'"

It was a wistful beginning to what turned out to be a fun, and funny, hour-long discussion onstage between Lucas, certainly one of the most successful filmmakers of all time, and "Daily Show" host Jon Stewart.

Billed as the "Main Event" of Celebration V, there's no doubt that the conversation kept the thousands on hand entertained--and educated. Stewart demonstrated his bona fides as a well-informed "Star Wars" fan, and Lucas didn't disappoint with his illuminating answers, and willingness to fill in some gaps in the 33-year-old "Star Wars" universe. The often stolid Lucas even opened up and laughed several times, cracked a few jokes, and showed a relaxed, human side he doesn't always display in public appearances.

And, committed to keeping the audience interested, Lucas and Stewart sprinkled a series of surprises throughout the hour, including unexpected appearances by Mark Hamill and Carrie Fisher, who played Luke Skywalker and Princess Leia, respectively, in the original three "Star Wars" films. Plus, Lucas excited the crowd of true believers by announcing that all six of the series' live-action films would be released on Blu-ray in 2011.

The origin of the names
I was fortunate enough to be sitting in the front row for the Lucas-Stewart tete-a-tete, and for me, it was a fun and fitting last bit of reporting on Road Trip 2010. Having traveled up and down the Northeast, and flown to Orlando for Celebration V, this was a big-league end to more than six weeks of interesting, educational, and often exciting destinations to write about and photograph.

If I'd had the unbelievably rare chance to be the one interviewing Lucas onstage, I'm not sure what I would have asked him. Stewart got around that conundrum by catering to the crowd and asking many fan-submitted questions, and simply following up with his own inquiries.

As any "Star Wars" fan knows, the saga is filled to brimming with a collection of creative names for characters, races, planets, starships, and more. Stewart asked where those names came from, and whether Lucas had a process for coming up with them.
Lucas joked that he often would come up with those names during the long parts of his work days when he was avoiding the task of writing, but eventually allowed that many of them, such as "ewoks," were derived from the name of elements in his life, such as the Miwok Indians, who had lived in the area of Northern California where Lucas resides. Asked where Darth Vader's name came from, Lucas said it was a term that, loosely, means "dark father" in Dutch.

Stewart then asked about what must have been difficult days while Lucas and his crew were making "Star Wars," when money was tight, when believers in his vision were few, and when the technical challenges were daunting.

"Well, it helps to be nuts," Lucas replied.

"I think we've just written the title to your autobiography," Stewart responded.

In all seriousness, though, Lucas said that the real secret to overcoming those long odds was a combination of a fondness for building things, an obsession for not letting others get in the way of his goals, and an unwillingness to care what the rest of the world thinks.
