The only known photo of Gene Roddenberry meeting George Lucas, taken at the Creation Entertainment/Starlog 10th Anniversary Star Wars Convention in 1987. Photo by Dan Madsen.
According to an interview with Madsen:
The story goes that you got the only picture taken of Roddenberry and George Lucas together. Is that true? Even if it's not, there's got to be a good story there.
The photo was taken at the first Star Wars 10th anniversary convention in L.A. that was put on by Creation. At the end, George came out to speak to the crowd and was surprised by Gene, who came out to congratulate him on the 10th anniversary. They were on stage for a short time and it was a historic moment. There were hundreds of people in the audience, so I’m sure someone snapped a photo of them. Most never saw the light of publication, though. It was pretty exciting to see my two heroes on stage together, something I thought I’d never see. I'm not sure if they ever saw each other again. It was quite a surprise when Gene walked out on stage and George, I think, was at a loss for words. He wasn't expecting that. It was one of those very cool moments.
