There are plenty of actors who dabble in directing, and there are plenty of directors who also famous for acting in their own movies. But what about famous directors who aren't actors but decide to go on the other side of a camera because of vanity or a favor to a friend?

There are many more of those than you would think, which gave us an abundance of choices for this week's episodes. From silly cameos to key supporting roles, we show the gamut of directors acting badly (or, sometimes, quite well.)
