Mike,
This critique will be coming in bits and pieces.
I've read half of your script and skimmed the second half. Will give it a more thorough read later.
I get the impression you are a serious screenwriter.
With that in mind, i will address your work with as much professional input as I'm capable of.
There will be some SPOILERS here, for those who have not read your script.
Please don't take offense to my criticisms, they are meant to stimulate thought.
And they are my opinion, so others might not agree.
You might not agree.
But if anything I say, or anybody else adds, inspires you to think of each scene, dialogue, etc. in a different way, than we've succeeded in helping you.
Since Story is king, I wonder how much thought you put into the story line.
If Deaza and Orthu are taking over the world, how does the FBI know this information?
How do they know when and where D and O are going to make their move.
The book is to raise the dead, which in turn will take over the world, if I'm not mistaken. But from what we've seen already of the walking dead, not to mention the vampires and werewolves, none poses much threat. Of course, you could be talking about masses of walking dead, which could be harder to control.
If monsters can be subdued with relative ease and the FBI knows this, why do they need to recruit gangsters and thugs? Why not just go down to Home Depot and buy a bunch of hammers and whack the crack out of the vamps and wolves???
The guy with the flame thrower can seemingly do the job by himself.
Thus, you've got to make your monsters almost indestructable.
Otherwise, why make them monsters. Monsters are monsters because they are badder, meaneer and tougher than humans. If they look like Tarzan but swing like Jane, than this won't be much of a horror movie.
But let's start with the opening scene.
I like your writing style. the exchange of words between Clark and Jimmy was ping-pong quick and fun.
I do think that you could set up the scene so that it says a bit more about the scenario and the characters.
Of course, the idea I have in mind might have no relevance to the rest of the story.
Before i go into that, if this book is so important, why send two guys -- one of them a losse cannon -- to retrieve the item? Wouldn't Paulie send an army of his best men??
If jimmy indeed killed a bunch of his fellow crew members, wouldn't he have been wasted a long time ago.
He's an old man, and you know what they say about old dogs.
Jimmy seems like a liability.
I wouldn't trust him to order pizza.
If I was the mob boss, Jimmy would be swimming in Lake Michigan.
Back to the opening scene.
The exchange between Jimmy and Clark seems to be about power.
But neither of them truly have power, because they are on an assignment by the don, Paulie.
So why are they arguing about who is in control?
It seems Paulie should have made that decision to avoid any conflicts.
If Jimmy is still employable, what does he know? What makes him special for this assignment?
I can say the same about Clark. When the FBI recruits him, why? What power does he have? What skills make him enticing to the Feds? he seems like a garden-variety punk with a big mouth.
I think that Jimmy and Clark have to possess special skills or talents.
Thus, they are chosen to get the book because of these abilities.
Maybe jimmy knows something the rest of us don't. Maybe he didn't kill his partners. maybe a vampire did.
To boost your opening scene, you might consider using visuals to punctuate what was said verbally.
Example:
Clark doesn't trust Jimmy because he's old, he's a loose cannon, he's disrespectful and he pretty much serves no purpose. If Clark knows Jimmy killed his partners, even if it's accidental, he should show his smarts by setting Jimmy up. Clark picks the restaurant and the time to meet. He arrives late and Jimmy is all pissed off because he's been sitting for two hours. They argue and they can only agree that neither man trusts the other. As a show of respect, each man places his gun on the table. Thus nobody pulls a gun under the table and gets crazy.
The waitress accidentally spills wine or spaghetti on Jimmy. She escorts him to the employee bathroom or whereever and helps him clean up. The waitress apologizes profusely. She escorts jimmy back to the table and brings him a bottle of wine, on the house.
Clark yells at the waitress for being new and stupid. She begs him not to complain to the manager.
Before Clark and Jimmy leave the restaurant, Clark slips the waitress slips a $50.
Now we suspect Clark and the waitress know each other and have set up Jimmy.
Later we learn Clark got Jimmy away from the table so he could empty the clip in Jimmy's gun. Now Jimmy is running around without bullets.
This is just an example of how you can show the way a person thinks and plans. Clark has to be cunning. he doesn't want Jimmy to go crazy on him and so he acts. He takes control. Now Clark is interesting. Now we see Clark as a thinking man.
You can always reverse this too, Maybe jimmy has something up his sleeve and takes action.
Think of ways to demonstrate how each character works. This adds interest and mystery. We neve know when one of your characters is going to plot against another. The twist works if we don't see it coming.
And tell me, why is Deaza walking around with the book anyway in the first encounter between he and Clark?
Was he transporting the book to a destination? Giving the book to somebody??
And how does the mob know that he will have the book when Jimmy and Clark steal it from him?
Some things to think about.
This jumps ahead a little, but I read somebody else's post questioning the hispanic gangsters. To break the stereotype mold, what if you made them all gay gangsters. Could be funny to hear these guys talk with a lisp and come off sounding like those guys on Queer [whatever] for the Straight Guy on Bravo.
Anyway, more later.
