It's the same with people knowing absolutely everything there is to know about an actor. I actually think the more personal information you have about an actor, the more you have to carve out for yourself when you go to a movie and see them in it.
There are three kinds of people in this world: 1) People who make lists, 2) People who don't make lists, and 3) People who carve tiny Nativity scenes out of pecan hulls. I'm sorry, there isn't really a third category; it's just that a workable list needs a minimum of three items, I feel.
