How did I miss this thread?
My first real convention experience (i.e., not a comic book swap meet billed as a convention) was a Star Trek convention held in my hometown. My gaming group got wind of its occurrence, and decided to attend en masse. The guests were Mark Leonard (Sarek) and Robin Curtis (Saavik in Star Trek III). Both were highly entertaining speakers, but the reason I'll always remember it is Robin Curtis.
I've always been a Saavik fan. The idea of a Vulcan/Romulan hybrid is, to me, even more intriguing than the Human/Vulcan pedigree of Spock. And I thought that Robin Curtis was a much better Saavik than Kirstie Alley by leaps and bounds. So, I was kind of excited to hear her speak. All during her Q&A, my friend kept threatening to raise his hand and say something to embarrass me. Being younger and less sure of myself, I was horrified at the thought of being humiliated in front of an actress whose work I really enjoyed. (I still get star struck, but not as bad.)
Later, after the Q&A and before her signing session, we were sitting outside near the snack bar and who should walk by but Ms. Curtis herself and her female companion. Immediately, my friend says he's going to go over there and meet her and tell her how star struck I am. My blood goes cold as he stands and makes his way over, saying loudly, 'Miss Curtis? Miss Curtis?'
So, I'm sitting there with my heart in my throat, my best friend is sitting next to me howling with laughter as my other friend speaks to Robin Curtiss, and is gesticulating wildly in my direction. And of course, she's looking right at me. So, I drag myself off the bench and ease closer, just knowing that she thinks I'm some crazy fan, and I'm starting to wonder myself. But, she turned out to be very nice, and very friendly, and we had a nice little chat before she had to go get ready to sign pictures.
Another interesting note: When ST3 came out, my sister went to an appearance of James Doohan at the mall. When he signed her picture, he asked her name, and when she told him, he said 'I have a daughter with that name,' which thrilled her no end. When I was getting pictures signed, I got one from Mark Leonard for my sister, and told him her name. He immediately replied, 'That's the same name as Jimmy Doohan's daughter. That's kind of cool.'
And it was.
