One of my favorite stories from her panel involved Will Wheaton; in between scenes, still dressed in their Starfleet costumes, they decided to explore the studio. The movie "Coming to America" starring Eddie Murphy was filiming. They snuck into the scene where the African dancers were perfoming...the director noticed and started yelling "cut, who is that, what are they doing there??!!". They ran out and didn't get caught. She says if you play the video and pause the screen you can see it...will have to put that on my Blockbuster list.
Gates was a last minute replacement for Johnathan Frakes, who was stuck in Maine because of weather. She flew in overnight, and after a quick coffee, was ready to go. Even though I had met her before, she was a worthy replacement.
I wasn't much of an original Star Trek fan, but I like Walter's character in Babylon5. While we were wating in line for the autograph room to open, he came down the line saying "visit Walter's table, visit Walter's table". Funny guy.
At dinner I sat at the table with Andrew Probert, who is credited with designing the Enterprise D. During the panel he explained how he re-arragned the engines from the orignal Enterprise to be more realistic from an engineering standpoint. He seems to take this approach with his work.
