Somewhat. A fully developed proposal will have a book with all that stuff, but OTOH it's a fact of life in Hollywood that you shouldn't spend too much money on that stuff before you go into production, for 2 reasons. One, it's a fast way to go broke. Two, you wouldn't have all that stuff to hand if you were trying to turn your friend onto a great film that you had seen and thought your friend should watch right now. Studio execs don't want to be distracted by eye candy or character sheets, they want to hear something that fires their imagination.
