Scriptwriting research 1: Slug lines
Recently I took a closer look into how to format a script so as to make it not only easier to follow but effective and succinct in it's use. I not only discovered about the format used (Courier sans font, 12pt size, black text on white background) but also about slug lines - which is specific directions used to say exactly what one wants to see in the scene: I will use these from now on in my screenplay.
