I just finished the first 4 chapters in "Great Films" by Costanzo. I never realized how much goes into making a film!! It is true that being able to see the pictures in front of you and to be able to hear the music does help to understand what is going on and what the character is thinking. With a book it is interesting to have the visuals described to you and to have to picture them in your mind as opposed to having the film do everything for you.
In chapter 3, the technology of film, I think it is very hard to remember what all of the bold faced words mean. There are so many details that a filmmaker has to understand. There are so many facets to a movie!! I didn't think that making a movie was simple, but I didn't think it was so complex either. Just for lighting alone there are 11 bold faced words that describe different kinds of lighting. This information definitely causes me to appreciate the work put into a film!
