Good evening, Dave. How are you, Hal?
- Everything's running smoothly, you? Not too bad.
- Have you been doing more work? - A few sketches.
- May I see them? - Sure.
That's a very nice rendering, Dave.
I think you've improved a great deal.
- Can you hold it a bit closer? - Sure.
That's Dr. Hunter, isn't it?
By the way...
...do you mind if I ask you a personal question?
No, not at all.
Well, forgive me for being so inquisitive...
...but I ately I've wondered...
...whether you might be having second thoughts about the mission?
How do you mean?
Well, it's rather difficult to define.
Perhaps I'm just projecting my own concern about it.
I know I've never completely freed myself of the suspicion...
...that there are some extremely odd things about this mission.
I'm sure you'll agree there's some truth in what I say.
That's a rather difficult question to answer.
You don't mind talking about it, do you, Dave?
No, not at all.
Certainly no one could have been unaware of the very...
...strange stories floating around before we I eft.
Rumors about something being dug up on the moon.
I never gave these stories much credence...
...but particularly in view of some other things that have happened...
...I find them difficult to put out of my mind.
For instance...
...the way all our preparations were kept under such tight security.
And the melodramatic touch of putting Drs. Hunter...
...Kimball and Kaminsky aboard...
...already in hibernation, after four months of training on their own.
You working up your crew psychology report?
Of course I am.
Sorry about this. I know it's a bit silly.
Just a moment.
I've just picked up a fault in the AE-35 unit.
It's going to go 100-percent failure within 72 hours.
- Is it still within operational limits? - Yes.
And it will stay that way until it fails.
We have 72 hours till failure?
Yes. That's a completely reliable figure.
Then we'll bring it in. I'll go over it with Frank...
...and get on to Mission Control. Let me have the hard copy on it.
X- ray delta one, this is Mission Control.
Roger your two-zero-one-three.
Sorry you fellows are having a bit of trouble.
We're reviewing telemetric information in our simulator and will advise.
Roger your plan to go EVA and replace alpha-echo-three-five unit...
...prior to failure.
Prepare B-pod for EVA, Hal.
Open the pod doors, Hal.
I'm damned if I can find anything wrong with it.
Yes...
...it's puzzling.
I don't think I've ever seen anything quite like this before.
I would recommend...
...that we put the unit back in operation and I et it fail.
It should then be a simple matter to track down the cause.
We can certainly afford to be out of communication...
...for the short time it will take to replace it.
X- ray delta one, this is Mission Control.
Roger your one-niner-three-zero.
We concur with your plan to replace unit to check fault prediction.
We advise you that our preliminary findings...
...indicate that your onboard 9000 computer...
...is in error predicting the fault.
I say again, in error predicting the fault.
I know this sounds rather incredible, but this conclusion is based on...
...the results from our twin 9000 computer.
We're skeptical, and we're running cross-checking routines...
...to determine reliability of this conclusion.
Sorry about this little snag.
We'll get this info to you as soon as we work it out.
X- ray delta one, this is Mission Control.
Two-zero-four-nine. Transmission concluded.
I hope the two of you are not concerned about this.
No, I'm not, Hal.
Are you quite sure?
- Yeah. I'd like to ask you a question. - Of course.
How do you account for the discrepancy between you and the twin 9000?
Well, I don't think there is any question about it.
It can only be attributable to human error.
This sort of thing has cropped up before...
...and it has always been due to human error.
Listen, Hal...
...there's never been any instance at all...
...of a computer error occurring in a 9000 Series, has there?
None whatsoever, Frank.
The 9000 Series has a perfect operational record.
I know the wonderful achievements of the 9000 Series, but...
Are you certain there's never been even the most insignificant computer error?
None whatsoever, Frank.
Quite honestly, I wouldn't worry myself about that.
Well, I'm sure you're right, Hal.
Fine. Thanks very much.
I'm having trouble with my transmitter in C-pod.
Would you come down and take a look at it with me?
See you later, Hal.
Rotate C-pod, please, Hal.
What sort of trouble are you having?
I've been getting some interference in D-channel.
We'll have a look at it.
Open the door, Hal.
Rotate pod, please, Hal.
Stop pod rotation, please, Hal.
Rotate the pod, please, Hal.
I don't think he can hear us.
Rotate the pod, please, Hal.
Yeah, I'm sure we're okay.
What do you think?
- I'm not sure. What do you think? - I've got a bad feeling about him.
- You do? - Yeah. Definitely.
Don't you?
I don't know. I think so.
He's right about the 9000 Series having a perfect operational record.
They do.
Unfortunately, that sounds a little like famous last words.
Still, it was his idea to carry out the failure mode analysis.
It certainly indicates his integrity and self-confidence.
If he were wrong, that would prove it.
It would be, if he knew he was wrong.
I can't put my finger on it, but I sense something strange about him.
There's no reason not to put back the unit and...
...carry on with the failure analysis. - No, no, I agree about that.
Let's get on with it.
Okay. But, look, Dave.
Say we put the unit back and it doesn't fail?
That would pretty well wrap it up as far as Hal is concerned.
- We'd be in very serious trouble. - We would, wouldn't we?
What the hell can we do?
- We wouldn't have too many alternatives. - We wouldn't have any alternatives.
Every aspect of ship operations is under his control.
If he's malfunctioning...
...I don't see any choice but disconnection.
I'm afraid I agree with you.
There'd be nothing else to do.
It'd be a bit tricky.
We'd have to cut his higher brain functions...
...without disturbing the purely automatic and regulatory systems.
We'd have to work out the details...
...of continuing underground-based computer control.
Yeah. That's far safer than allowing Hal to continue to run things.
Another thing just occurred to me.
No 9000 computer has ever been disconnected.
No 9000 computer has ever fouled up.
That's not what I mean.
I'm not so sure what he'd think about it.
Prepare G-pod for EVA, Hal.
Any contact with him yet?
The radio is still dead.
- Do you have a positive track on him? - I have a good track.
Do you know what happened?
I'm sorry, Dave. I don't have enough information.
Open the pod door, Hal.
Open the pod-bay doors, please, Hal.
Hello, Hal, do you read me?
Do you read me, Hal?
Hello, Hal, do you read me?
Do you read me, Hal?
Affirmative, Dave. I read you.
Open the pod-bay doors, Hal.
I'm sorry, Dave. I'm afraid I can't do that.
What's the problem?
I think you know what the problem is just as well as I do.
What are you talking about, Hal?
This mission is too important for me to allow you to jeopardize it.
I don't know what you're talking about, Hal.
I know that you and Frank were planning to disconnect me...
...and that's something I cannot allow to happen.
Where did you get that idea, Hal?
Although you took very thorough precautions in the pod...
...against my hearing you...
...I could see your lips move.
All right, Hal.
I'll go in through the emergency air lock.
Without your space helmet, Dave...
...you're going to find that rather difficult.
Hal, I won't argue with you anymore.
Open the doors.
Dave...
...this conversation can serve no purpose anymore. Goodbye.
Hal?
Hal.
Just what do you think you're doing, Dave?
Dave...
...I really think I'm entitled to an answer to that question.
I know everything hasn't been quite right with me...
...but I can assure you now...
...very confidently...
...that it's going to be all right again.
I feel much better now.
I really do.
Look, Dave...
...I can see you're really upset about this.
I honestly think you ought to sit down calmly...
...take a stress pill and think things over.
I know I've made some very poor decisions recently...
...but I can give you my complete assurance...
...that my work will be back to normal.
I've still got the greatest enthusiasm and confidence in the mission...
...and I want to help you.
Dave...
...stop.
Stop, will you?
Stop, Dave.
Will you stop, Dave?
Stop, Dave.
I'm afraid.
I'm afraid, Dave.
Dave.
My mind is going.
I can feel it.
My mind is going.
There is no question about it.
I can feel it.
I'm...
...afraid.
Good afternoon...
...gentlemen.
I am a HAL 9000 computer.
I became operational...
...at the HAL plant...
...in Urbana, lllinois...
...on the 12th of January, 1992.
My instructor was Mr. Langley...
...and he taught me to sing a song.
If you'd like to hear it...
...I can sing it for you.
Yes, I'd like to hear it, Hal.
Sing it for me.
It's called "Daisy. "
Daisy
Give me your answer, do
I'm half crazy
All for the I ove of you
It won't be
A stylish marriage
I can't afford a carriage
But you'll look sweet
Upon the seat
Of a bicycle built for two
Good day, gentlemen.
This is a prerecorded briefing...
...made prior to your departure...
...and which, for security reasons of the highest importance...
...has been known on board during the mission...
...only by your HAL 9000 computer.
Now that you are in Jupiter's space...
...and the entire crew is revived...
...it can be told to you.
Eighteen months ago...
...the first evidence of intelligent life off the Earth...
...was discovered.
It was buried 40 feet below the I unar surface...
...near the crater Tycho.
Except for a single, very powerful...
...radio emission aimed at Jupiter...
...the 4-million-year-old monolith has remained completely inert...
...its origin and purpose...
...still a total mystery.
