Star Trek: The Next Generation's Michael Dorn, Brent Spiner, Levar Burton, and Jonathan Frakes answer questions at the Wizard World Austin Comic Convention. I apologize for the lack of videotaping skills.
I must be missing something because these guys or actors are boring old farts. I enjoyed their characters on TNG but as real people talking at conventions seems to me as a complete waste of their time. I am a Aussie Trekkie. It must be an American thing. No offense.
They were 25 years younger (counting from the time you wrote your negative sentence) on TNG. Go figure. Everyone ages. Even actors. It doesn´t matter their nationality. And so what if they become a little egocentric? You would probably be the same if millions of people adored you and you could do no wrong. PS: Just realized we have the same avatar.
