Quickly son, they’re on the move.
41. OMITTED
42. INT. CAVE DWELLING – MAIN LIVING AREA

The small, spartan hovel, is cluttered with desert junk, but still manages to radiate an air of time worn comfort and security. Luke is in one corner repairing Threepio’s arm, as old Ben fiddles with Artoo.

BEN
Now let’s see if we can’t figure out what you are my little friend and where you came from.

LUKE
I saw part of a message he…

Luke is cut short, as the recorded image of the beautiful young rebel princess is projected from R-2′s face.

BEN
Yes, I seem to have found it.

Luke stops his work as the lovely girl’s image flickers before his eyes.
PRINCESS LEIA
General Obi-wan Kenobi, I present myself in the name of the royal family of Alderaan, and the Alliance to restore the Republic. I break your solitude at the bidding of my father Bail Antillies, Viceroy and Chairman of the Alderaan system. Years ago Commander you served the Republic in the Clone Wars. Now he begs you to aid us again in our most desperate hours. He would have you join him on our home planet Alderaan. You must go to him! I regret I am unable to present my father’s request to you in person… my mission to return with you has failed, information vital to the survival of the Alliance has been placed in this droid… my father will know how to retrieve it. I plead with you to see this R-2 unit safely delivered to Alderaan. You must help me, you are my last hope.

There is a little static and the transmission is cut short Old Ben leans back and scratches his head. He silently puffs on a tarnished chrome water pipe. Luke has stars in his eyes.

LUKE
She is so… terrific. Commander?? You fought in The Clone Wars??

BEN
Oh yes… I was once a Jedi knight… like your father.

LUKE
Jedi knight?? My father didn’t fight in the wars. He was a navigator…. on a spice freighter.

BEN
Oh so your Uncle told you .. He didn’t agree with your father’s ideals, thought he should have stayed here and not gotten involved. He was always afraid your father’s adventures might influence you ..

LUKE
I wish I’d known him…
BEN
He was the best starpilot in the galaxy and a clever warrior… he was a good friend. I understand you’ve become quite a good pilot yourself… in many ways you’re much like your father.

Ben gets up and goes to a chest, where he rummages around.

BEN (cont’d)
Which reminds me, I have something here for you. When you were old enough, your father wanted you to have this. I tried to give it to you but your uncle wouldn’t allow it. He believed you might follow old Obi-wan on some idealistic crusade as your father did.

Luke finishes repairing Threepio and starts to fit the restraining bolt back on, Threepio looks at him nervously, Luke thinks about the bolt for a moment then puts it on the table. Ben shuffles up and presents Luke with a short handle with several electronic gadgets attached to it.

THREEPIO
Sir, if you’ll not be needing me, I think I’ll shut down for a while.

LUKE
Sure, go ahead.
(to BEN)
What is it?

BEN
Your father’s light saber. At one time they were widely used… I believe they still are in some parts of the galaxy…

Luke pushes a button on the handle and a long laser beam shoots out about four feet, flickers there.

BEN (cont’d)
This is the weapon of a Jedi Knight… not as clumsy or random as a blaster. An elegant weapon… for a more civilized time.
(He begins to remember)
For over a thousand generations Jedi Knights were the most powerful, most respected force in the galaxy… the guardians of peace and justice in the old republic. That was when the galactic senate ruled the galaxy before the dark times, before the empire.
Luke hasn’t really been listening.

LUKE
How did my father die?

BEN
He was betrayed and murdered… by a young Jedi, Darth Vader. A boy I was training, one of my brightest disciples, one of my greatest failures… He used the power of the force for evil – to help the empire hunt down and destroy the Jedi knights, now the Jedi are all but extinct. Vader was seduced by the dark side of the force and it consumed him.

LUKE
The force??

BEN
The force is… let’s just say the force is something a Jedi deals with. It is an energy field created by living things – it surrounds us – it binds the galaxy together – it directs our actions. Knowledge of the force is what gives a Jedi his power. You must learn the ways of the force if you are to come with me to Alderaan.

LUKE
Alderaan!?? I’m not going to Alderaan. I’ve got to get back home! It’s late, I’m in for it as it is… you can take the droid… I’ll think of something to tell my uncle… I hope…

BEN
I need your help, Luke. I’m afraid I’m getting too old for this sort of thing ..

LUKE
I can’t get involved, I’ve got work to do. I mean I don’t like the empire… I hate it… but there is nothing I can do about it right now… it’s all such a long way from here.

BEN
That’s your uncle talking.
LUKE
Oh, my uncle. How am I going to explain all this.

BEN
Remember, the Force is with all men, it binds them together. The suffering of one is the suffering of all.

LUKE
I can take you as far as Anchorhead. You can get transport there to the spaceport at Mod Eisley or wherever you’re going…

BEN
You must do what you feel.

LUKE
Right now I don’t feel too good…
