I find that I don't like Book trailers with actors running back and forth. There have been a could that I liked. I want to see this TV show... Or the movie?

Here are two more examples. (There were 4 in my previous posting on this subject)
This video may be inspiring and amusing. It is a format for making a movie trailer.
