Okay, you guys for them all and this has turned into Rag on Hollywood, which is pretty easy. Let's turn this on it's side - YOU write a scene where the movie could progress and the gun scene would be accurate in YOUR eyes.
I have always thought that the best hitman/sniper scene for a movie where the "target" HAD to live, and it had to take place in the City, would go something like this....
Bad Guy is sequestered INSIDE a building with a store front, or inside an apartment on a low level floor to eliminate down angle. ( Snipers don't shoot from rooftops unless they are cops with a barricade situation or they don't intend on being snipers for long. No Silhouetting
, no open rooftop of vast expanse space that anyone could walk up onto at any moment.
The Bad Guy sniper is set in place and knows that his intended target will be at an outdoor cafe', meeting, say an informant or other person.
Previously we have seen the B/G actually sitting in the same outdoor cafe the same day as the hit is to take place and he subtly places some sort of indicated, like a chewing gum wrapper that is not wadded up but open, under the table or on the ledge of the cafe' fascia.
So, target and informant sit down at the cafe' and order, coffee, what else? Nobody ever eats in the movies anymore.
Hitman is snugged in his hide and we see him open the mail flap on the door, or he cracks the sliding window about 1 inch and digs in behind the rifle.
We see him re-range the target with a laser range finder and compare it to his notes right on the left side of the rifle.
Target and informer have coffee delivered in these huge open top mugs and you can see the steam coming off the top, with just a slight breeze blowing. Small talk ensues as the waitress sets down both cups of coffee, takes their order for whatever small salad they are going to pretend to eat, because actors don't actually eat anything good on screen.
Hitman is seen scoping back and forth across the Cafe' and we see him stop on his gum wrapper, which has moved slightly Left to Right just before some bus boy with a goody-goody complex picks it up and puts it in his little bus boy tub. Bastard!
Blah, Blah, Blah talk about whatever is the information the audience needs to be filled in on.
The Hitman is now scanning over the table and sees the steam coming off the coffee with the same Left to Right movement that the gum wrapper moved, so he pauses and makes a one click adjustment to his windage on the scope, to compensate.
As he's adjusting the waitress returns with the salads, places them on the table and offers fresh cracked pepper across the top. The target declines as he is allergic, but the informant says they will take a little.
We zoom in on the grinder as the cracked pepper is being dropped on the salad and we see some fluttering across to the targets face.
Cut scene to a close up on the trigger finger as Hitman takes up slack with his crosshairs firmly planted behind the ear on the target.
Dude sneezes as the round is fired, causing his head to move with an involuntary reaction and the round whizzes past only to smash the front window of the Cafe' - which alerts the target and the resulting "RUN!"
