but in a different future.
Father?
Once this core material...
is fully introduced
into the control console...
Core material.
If we could get that
back to our Jupiter...
I will open a doorway
stable enough...
for one person to take
one trip through time...
and space as well.
Commence proto-generation.
Cool, huh?
Today, I will change history.
I'm gonna go back to that day
you dragged us into space.
I'll stop the ship
from taking off.
I'll save the family.
Earth, October 1, 2058.
Target lock confirmed.
Excellent.
Son...
Look around.
The force of your time machine
is ripping this planet apart.
These violent distortions
in time...
are being caused
by your experiment.
What if it has the same effect
on Earth?
What if, in getting home...
you destroy Earth
in the process?
I know you mean well.
I'm going home.
I'm going to save the family.
You've gotto listen to me.
I'm your father's!
My father?
Let me tell you about my father.
I'll never forget
that morning 20 years ago.
What was it you said?
'I'm coming back.
I  promise.'
You promised...
and you never came home.
My father's not
coming to the rescue.
What do you think you're doing,
young man?
Let me tell you about life.
Around every corner,
monsters wait.
I know. I am one.
We monsters have no fear
in devouring little boys.
To survive, you must be
fully prepared to kill.
I can do it.
Can you?
Listen to me, my child...
I've crossed this world
with you...
risked my life,
but I would not throw it away.
Who knows what dangers
lie ahead?
You can't protect us.
I can.
I will.
Gimme the gun.
Enable gun for all users.
Voiceprint confirmed.
A brief lesson in survival
on this world or any other--
never trust anyone.
Especially me.
It's almost time.
I  hope it works.
Never fear...
Smith is here.
Don't move,
Professor Robinson...
or this peculiar family reunion
will be tragically brief.
I'll ask you
to step away from that.
It's a time machine,
you idiot.
I had hoped to take over
the ship with this.
One of life's little ironies.
Let's try this dance again.
You are the puppet,
I  am the puppeteer.
Do try to get it right
this time.
Robot, you will respond
to my voice alone.
Affirmative.
We need electric disrupters.
That's good, gargantuan.
You did it.
Just like I imagined.
You linked
the dimensional sifter...
to the navigational array.
That's how it can be in
the same place at the same time.
but the spatial delivery system,
the targeting laser...
I never thought of those.
the future is never what
it seems like when you're 10.
Say good-bye to your past!
Your future lies with me.
I'm going home in your place.
What are you grinning at?
Look around you...
at this hostile world.
Do you think a boy
could have survived all alone?
Never fear...
Smith is here.
It's Dr Smith.
Hello.
How nice to see me again
after all these years.
Confused?
Have I changed?
The spider's sting had some
unexpected side effects.
My unique gifts
gave me an advantage...
in this quarrelsome world.
After the women were savaged...
I became the father
Will never had.
Two decades of agony taught me
the error of my ways.
But you, your crude ambition
fills me with seIf-loathing.
You see,
I  have looked within me...
and what I see is you!
I never liked me anyway.
Robot, kill them all.
Wait.
Dr Smith, please.
Don't.
Very well.
Robot, take them inside
and keep them there.
If they move...
then kill them.
Proceed or be destroyed.
Nothing works.
I'll draw his fire,
you grabWill and get out.
Halt!
Stop!
Do you remember me?
Do you remember what I
taught you about friendship?
I need you to help us now,
because we're friends.
Logic error.
Friendship does not compute.
Forget logic.
Act with your heart.
Robot has no heart.
Robot is powered by
a fusion pulse generator.
Every living thing has a heart.

to remove all emotion.
