A few weeks ago an idea struck me how we could improve our script writing and film making skills:
Take a film. Look at every scene, every cut. Write down in script layout what the script must have looked like that the scene is based on. Go on until the end of the film.
Best case scenario: compare it with the actual script (there are hundreds of scripts published on this site)
I suspect this exercise could give us more confidence in how to layout a script, what information must be or not be included, etc. And because we would have seen every scene and written down every page, we would have gained much more knowledge about how films are generally made.
