Why Do Actors Think They Can Direct?
Time after time I see actors stepping into the director's chair and failing miserably. There are exceptions of course, Clint Eastwood comes to mind, but the majority of actors I've seen trying to direct typically produce fairly derivative work.
Directing is incredibly difficult, and very few people do it well, which is why I question why so many actors feel a need to try it, many of whom, quite frankly, are as dumb as a post.
