I couldn't agree with you more Problem Eliminator. Meeting Bond stars outside those conventions is so much cooler. The very first time I met Maud Adams was at a Barnes and Nobles in Santa Monica and it was incredible. I was there working on a script and because I had nothing else for her to sign, I asked her if she wouldn't mind signing the cover of the screenplay. After finding out I was studying film at UCLA she wished me luck with my career! Me, blessed by Octopussy herself! Funny thing is that a few months after that, I saw her again at the Hollywood Collectors Show, where, before I even said something, she looked at me and went "Hello again!". It was the coolest thing.
I also met Famke Janssen at Chateau Marmont, after my sister and I were playing with this cute little puck only to find out two minutes later it was Famke Janssen's dog! She and I had the greatest chat in Dutch (both hers and my mother language). So you see, meeting those Bond stars outside conventions is not that impossible after all ...
As for some stars not showing up at the Hollywood Collectors Show Athena, it doesn't surprise me. The organizers have been know to promise names at the show that then turn out not being there ... because they were never told! I remember an instance a few years ago, where Danny Bonaducci found out that he was going to be at one of their shows and he had never been contacted. But meanwhile, they had advertised it everywhere ... Who knows, maybe the Sir Roger Moore rumor was started by them...
