Much of the SCENE HEADING could be incorporated in the ACTION. Also don't repeat in the ACTION what is in the HEADING. The back is mentioned in both places, this is redundant.
THE PRESENT is unnecessary in the HEADING unless you are returning from the past or future.
My preference would be mixing the description into the action. For example, you wrote:
LUIGI GIANNINI (28, tall, handsome, blue-eyed,
broad-shouldered, handlebar mustache). As he walks, LUIGI
takes his napkin out from under his chin. Wiping his hands
and mouth, he stains the napkin with red pasta sauce.
I would write it something like:
Twenty-eight year old, tall, and handsome LUIGI GIANNINI walks and takes his napkin and wipe his hands and mouth. He stains the napkin and his handlebar mustache with red pasta sauce.
Or something like that. Wherever you can introduce descriptions within the action. This is NOT alway practical though. You must decide and how to work it into the ACTION paragraphs.
I panic over "ING" words especially when an "IS" is in the same sentence. For example you wrote:
GENE is peering out through the glass doors: the street is
I would suggest:
GENE peers through the glass doors at the deserted street.
DUMPING the "IS" and "INGs" gives the sentence more strength.
Of course, it will NOT be practical to dump all the INGs. But try to dump some or more.
I am on page four and the many SUPER DUPER SCENE HEADINGs thus far is causing my teeth to grind and my heart to flutter. Will I be alive at page 10?
Pg 4. "ROLL CREDITS." I am about to call 911. NOT ever on a spec script. SHOOTING script - YES.
Wayne, you have a STORY developing here. I recommend a re-write and try the suggestions I gave. There are a few ADVERBs I would dump as they weaken sentences. Look for those words with that ugly "ly" tail and rewrite many of them out.
Good luck Wayne.
