(about annoying experiance with certain Trekkies)
John de Lancie: Yes, often times people will set up their little, or I should say their 900mm lens on a tripod and make you think you're in some kind of photoshoot. The other thing I find annoying is when I'm trying to make a phone call in an airport and people are actually tapping me on the shoulder. I've actually had people follow me into the restroom and take pictures of me. It was embarrassing. Since I was in the women's restroom. And they were security guards. But other than that, it's been fun.

(his advice about acting)
John de Lancie: Spend everyday acting by either reading out loud or getting involved in community theater or creating your own show or watching other people act. Think of acting as a sport that has to be done rather than a mind-set.
