Yes. Oh, I should elaborate?? Being a fan of "bookends", I selected a VISUAL PROP to play a role in the opening and final scenes. While the prop remains the same, the circumstances surrounding my protagonist's use of it will differ vastly, thereby signalling the change that's taken place over the course of the story. My first scene (part of page one) should go a long way in establishing my heroine and her world, her lot in life, her quirks, what drives her, what's missing. It should also go a long way in establishing my unique screenwriting voice. At least that's my hope and intention...

Yup. It was originally going to begin with one scene, but I've now decided to skip past that fairly cliched moment and open a few minutes later, when my heroine's already done something that's likely to get her arrested and has no idea where to turn...

Yes, in the thick of the action - I want the audience to meet the protagonist in the thick of things - also I want it to be a place where I can recall it later to tie it together for the reader. I've got a good sense of where I will begin.

One thing to consider is what do we mean by "begin"? We can be specific and say the first scene or few continuous scenes. Or we can take a broader view and refer to what I call The Opening, essentially the set-up of the story's Set-Up. Oftentimes, they are one and the same. Other times, the first scene or few scenes is only part of The Opening. It all depends on the type of story, the number of characters, the central conceit, and so forth.
