If you are writing comedy screenplays, here is a short document that is worth your time to read. It’s by television writer David Evans. I have mixed feelings about “laws” and “rules” in art, but generally these things are simply guidelines on how to go about the work. One of the laws here is a “step sheet.” That is simply another term for an outline.
I also have a post based on the writing of Kurt Vonnegut. Eight Rules of Comedy
If you like this, you may want to check out my book about physical comedy, it’s full of valuable lessons you won’t find anywhere else.
