This is my ideal start. I had posted it in a thread with my script I never finished.
-Street in Gotham-
(raining)
A police car pulls up to the street. Two men exit. One is Lt. James Gordon. The other is Sergeant Harvey Bullock.
BULLOCK:
This the place, Jim?
GORDON:
(turns on a flashlight)
Yeah Bullock. Someone called in saying they heard screams and laughter.
BULLOCK:
You sure?
GORDON:
When youve been here as long as I have, youll see some crazy-
(a trash can falls in an alley way. GORDON and BULLOCK turn and take out their guns)
BULLOCK:
Im going in.
GORDON:
Bullock, wait.
BULLOCK:
(he slowly enters the alley way and sees a man kneeling over a body. BULLOCK takes out his flashlight and shines it on the mans face.
WHAT THE-!
(BULLOCK jumps back as he sees the mans white face and sinister grin. The man runs around the corner laughing maniacally. BULLOCK runs after him. When he gets to the end of the alley, the man is gone)
GORDON:
What was it, Bullock?
BULLOCK:
I dont know. You check the body?
GORDON:
Yeah. Its another one.
(he shins his flashlight on the body)
Multiple stab wounds, mutilated face, and a Joker card.
BULLOCK:
Ill go call it in.
(he exits the alleyway and heads to the car)
GORDON:
(he looks up to the sky and says to himself)
Youre never around when-
(BATMAN glides down from a rooftop and lands on a fire-escape)
The rest isn't that great.
