"BATMAN RETURNS" by Daniel Waters [with revisions by Wesley ...

INT. A STUFFY MANSION--A NIGHT ABOUT FORTY YEARS AGO
The viewer floats through an overbearing mansion and
up its sweeping staircase to where a stern man in
conservative dress is pacing back and forth, smoking a
cigarette in a cigarette holder. He is the FATHER. The
throes-of-labor pants and moans of the MOTHER can be
heard from down the hall.
Now, eerie Gaas and Goos chill the air. The Father stops
and gapes the cigarette holder out of his mouth to see a
dazed NURSE shuffle out of the birth room and disappear
down the hallway.
A TRAUMATIZED DOCTOR next wanders out. The Father runs
past him into the room. The viewer remains outside and
hears the Father's subsequent screams.
INT. MANSION LIVING ROOM--CHRISTMAS EVE PAST
A bizarrely corrugated Cage sits amid the plush, period,
and Christmased-up surroundings of the mansion. With
their backs turned to the sickly squeals emerging from
the Playpen from Hell, Father and Mother, holding
martinis, look out a window of gentle snowfall, with
bloodshot eyes. A 50's-type radio warbles "Santa Claus
is coming to Town."
A strange pair of eyes peer from the cage. Taking the
point of view of the eyes from inside the playpen, one
sees the mansion's Christmas tree from between the dark
cage slats.
GIDDY YULETIDE SINGERS
"He knows when you are sleeping,
he knows when you're awake..."
The family cat skulks past the cage -- almost. Without
warning, the cat is yanked -- so fast and powerfully it
seems that it's been sucked -- through the bars, into the
cage. A feline SCREAM, then sickening silence.
With dead syncopation, Mother and Father finish off their
martinis, and plop the empty glasses down.
