Ever notice how when people watch a tv show or a movie and they recognize an actor, they whisper to their friend or partner, "Hey, that's the guy from the other movie!" Or, "She was also the one who played so-and-so in that show back in the 80's!"
I admit it, I'm one of those people. But think about it, we say those things in such an excited way. I mean we are so SURPRISED that an actor or actress has been in something ELSE. Uh, that's kinda their job, so why are we so surprised when we see them elsewhere?
