I should start off by saying I mostly write action-adventure novels - 80k words plus. One of my guiding principles has always been: don't do anything that could not be tranferred to screen. This is not because I want my story to one day be a movie, but it stops me from telling too much to the audience. And I don't mean picturing scenes before I write them, I literally mean doing nothing that can't be shown. For example, rather than telling what a character is like, I will try and construct a scene or a conversation that shows all the character's attributes, tendencies, etc. What does anyone think are the disadvantages of this approach? And I'm looking for personal opinions as much as technical opinions. P.S. I should add - I have recently been made aware of the re-read. When writing in movie form it can sometimes take a bit longer to introduce characters, which I like, as it gives a better chance for people to get to know a character in their natural habitat, rather than just being told what they're like. However, during the re-read, the reader will know the characters and want to get right into the action.
