The Power of Descriptive Words

In the last episode of Doctor Who, David Tennant monologues about how he doesn't want to do it. The people holding those cameras are good enough cinematographers that if they had given him 10 seconds and the script screenwriter had said here's your motivation, make that face you could have pulled it off. One of the things is the descriptive words that you use. For instance, if he needs to sit down in a chair and the chair is repulsive to him, instead of saying the chair was repulsion to him, you can use descriptive words that make it clear that it's a repulsive chair.
