Acting, thank you
Ever watch a movie and see an actor or actress and think, "Cool I have always liked that actor. This movie will be good." And then realize that you have never seen that actor/actress before. It's a weird phenomenon. Actors that that has happened to me with include, Jack Black on Cable Guy and Steve Zaun on That Thing You Do. I was sitting there watching the movie thinking what have I seen these guys in before. They were great. But I had never seen them before in any movie. Strange indeed.
