In my opinion, along with O’Bannon, a lot of credit for Alien’s writing has to go to Walter Hill and David Giller, who rewrote the script (but received no credit so people forget they did).
Their script is a thing of beauty, one of the bests I’ve ever read.
As a comparison:
[details=O’Bannon’s opening]FADE IN:
EXTREME CLOSEUPS OF FLICKERING INSTRUMENT PANELS. Readouts and digital
displays pulse eerily with the technology of the distant future.
Wherever we are, it seems to be chill, dark, and sterile. Electronic
machinery chuckles softly to itself.
Abruptly we hear a BEEPING SIGNAL, and the machinery begins to awaken.
Circuits close, lights blink on.
CAMERA ANGLES GRADUALLY WIDEN, revealing more and more of the
machinery, banks of panels, fluttering gauges, until we reveal:
INTERIOR - HYPERSLEEP VAULT
A stainless steel room with no windows, the walls packed with
instrumentation. The lights are dim and the air is frigid.
Occupying most of the floor space are rows of horizontal FREEZER
COMPARTMENTS, looking for all the world like meat lockers.
FOOM! FOOM! FOOM! With explosions of escaping gas, the lids on the
freezers pop open.
Slowly, groggily, six nude men sit up.
ROBY
Oh... God... am I cold...
BROUSSARD
Is that you, Roby?
ROBY
I feel like shit...
BROUSSARD
Yeah, it's you all right.
Now they are yawning, stretching, and shivering.
FAUST
(groans)
Ohh... I must be alive, I feel dead.
BROUSSARD
You look dead.
MELKONIS
The vampires rise from their graves.
This draws a few woozy chuckles.
BROUSSARD
(shakes his fist in the
air triumphantly)
We made it!
HUNTER
(not fully awake)
Is it over?
STANDARD
It's over, Hunter.
HUNTER
(yawning)
Boy, that's terrific.
STANDARD
(looking around with a grin)
Well, how does it feel to be rich
men?
FAUST
Cold!
This draws a LAUGH.
STANDARD
Okay! Everybody topside! Let's get
our pants on and get to our posts!
The men begin to swing out of the freezers.
MELKONIS
Somebody get the cat.
Roby picks a limp cat out of a freezer.

Walter Hill's
SOMETIME IN THE FUTURE:
INT. ENGINE ROOM
Empty, cavernous.
INT. ENGINE CUBICLE
Circular, jammed with instruments.
All of them idle.
Console chairs for two.
Empty.
INT. OILY CORRIDOR - "C" LEVEL
Long, dark.
Empty.
Turbos throbbing.
No other movement.
INT. CORRIDOR - "A" LEVEL
Long, empty.
INT. INFIRMARY - "A" LEVEL
Distressed ivory walls.
All instrumentation at rest.
INT. CORRIDOR TO BRIDGE - "A" LEVEL
Black, empty.
INT. BRIDGE
Vacant.
Two space helmets resting on chairs.
Electrical hum.
Lights on the helmets begin to signal one another.
Moments of silence.
A yellow light goes on.
Data mind bank in b.g.
Electronic hum.
A green light goes on in front of one helmet.
Electronic pulsing sounds.
A red light goes on in front of other helmet.
An electronic conversation ensues.
Reaches a crescendo.
Then silence.
The lights go off, save the yellow.
INT. CORRIDOR TO HYPERSLEEP VAULT
Lights come on.
Seven gowns hang from the curved wall.
Vault door opens.
INT. HYPERSLEEP VAULT
Explosion of escaping gas.
The lid on a freezer pops open.
Slowly, groggily, KANE sits up.
Pale.
Kane rubs the sleep from his eyes.
Stands.
Looks around.
Stretches.
Looks at the other freezer compartments.
Scratches.
Moves off.
INT. GALLEY
Kane plugs in a Silex.
Lights a cigarette.
Coughs.
Grinds some coffee beans.
Runs some water through.
KANE
Rise and shine, Lambert.
INT. HYPERSLEEP VAULT
Another lid pops open.
A young woman sits up.
LAMBERT
What time is it.
KANE
(voice over)
What do you care.
INT. GALLEY
Pot now half-full.
Kane watches it drip.
Inhales the fragrance.
KANE
Now Dallas and Ash.
(calls out)
Good morning Captain.
DALLAS
(voice over)
Where's the coffee.
KANE
Brewing.
LAMBERT walks into the kitchen.
Pours herself a cup.
The second one (those descriptions!!!) is much more evocative of the final film and really nails the atmosphere the final movie relied on.
