I was watching the original series and got to "I am your father". I thought: is this something the author planned all along or thought of while writing The Empire Strikes Back?

I'll let someone else answer it, but the short answer is "No, not always, but yes, during preproduction of ESB" – Wad Cheber Jan 28 at 1:26
My first thought when I read the subject was "Well, family planning is important!" – Jane S Jan 28 at 2:55
Possibly related, but I'm pretty sure they also didn't intend Luke and Leia to be siblings in the first movie, since they were originally intended to be romantically engaged... – Darrel Hoffman Jan 28 at 15:50
I recall asking a loooong time ago (back in the 90's) on a SW forum this same question. My realization was that "Darth Vader" sounds a lot like "Dark Father", especially since "Vater" is father in German. Anyway, I do recall that someone referenced an interview where Lucas stated that he'd been rolling around such ideas since the beginning of ANH, but nothing was ever concrete. It wouldn't surprise me if that were both not true and that Lucas did say it. He's been known to contradict himself before telling the history of his mythology. – RLH Jan 29 at 12:31
Also, I see that p. 172 of The Making of Star Wars quotes Lucas saying of the name "That's just another one of those things that came out of thin air. It sort of appeared in my head one day. I had lots of Darth this and Darth that, and Dark Lord of the Sith. The early name was actually Dark Water. Then I added lots of last names, Vaders and Wilsons and Smiths, and I just came up with the combination of Darth and Vader." – Hypnosifl Mar 9 at 22:50

Prowse (the actor who played Vader) was originally told to reveal that it was Obi-Wan who killed Luke's father.

However, the original writer of the script that would become Empire Strikes Back, Leigh Brackett, died before finishing the final draft.

After Leigh's death, Lucas took over writing the script. It was received poorly, likely spurring on the revisions.

Of course, the twist was done by filming and even the actor playing Vader was basically kept unaware of the twist.


Original dialogue: "Obi-Wan killed your father."

Well, that would also be true, you know, from a certain point of view... – tilley31 Jan 28 at 2:01
I don't think the Prowse thing is a very strong argument. From what I've read, the reason they had Prowse say that was because they wanted to avoid the secret getting out (due to either Prowse or the crew letting it slip), and they knew Prowse's line was going to be dubbed over by James Earl Jones later. The point about multiple script drafts is better, but could do with some elaboration (this article has a lot of detail on the prior script, in which Luke actually met the spirit of his father). – Hypnosifl Jan 28 at 6:26
It would have been amazing if Obi-Wan had actually killed Luke's father. – Azor-Ahai Jan 28 at 8:03
@Azor-Ahai he so almost did – Cearon O'Flynn Jan 28 at 8:55
@CearonO'Flynn The funny thing is Darth Vader actually thinks this way. He feels Anakin is dead. – Mr Lister Jan 28 at 9:33

The idea of Vader being Luke's father came about in the second draft of The Empire Strikes Back.

From the annotated screenplays:

The notion of Vader being Luke's father first appeared in the second draft. Vader became attracted to the dark side while he was training to become a Jedi. He became a Jedi and killed most of the Jedi Knights. Ben fought Vader and pushed him down a nuclear reactor shaft. One of his arms was severed, and Ben believed he had killed Vader; in fact Vader survived and became a mutant.

A mutant, huh? That's new. – DCShannon Jan 28 at 4:32
I was so disappointed with Ep. III when "He [...] killed most of the Jedi" became "clone troopers killed most of the Jedi and he slaughtered children". I was looking forward to that originally promised battle since before the prequels were ever officially going to happen, and still feel that it is the most disappointing aspect of the prequels, with lots of disappointment to choose from. – Jason Jan 28 at 4:38
@DCShannon Technically, it's old. – JAB Jan 28 at 14:17

@user1717828 You better get a lawyer started on securing you the rights to that property, quick. That's a billion-dollar franchise if I've ever heard of one. – iamnotmaynard Jan 28 at 15:56

While the commitment to reveal the villainous Darth Vader as Luke's father was officially made in the second draft of The Empire Strikes Back, elements of a Darth-Vader-like character being Luke's father were present in the very first drafts of the first film's screenplay, back when it was going to be called The Star Wars. From the Wookieepedia entry for Kane Starkiller (father of Annikin Starkiller, the character who would later be renamed Luke Skywalker):

By the second draft, he becomes known simply as "The Starkiller" and he is the father of Luke Starkiller; he survives to the end of that version and is not a cyborg. In the following story synopsis, he is deleted and replaced by a crazy old man encountered on the road. The notion that Luke's father was a cyborg was incorporated into the story of Darth Vader. Coincidentally, Kane's cyborg body had a chest plate on his torso that resembled a similar chest plate on Vader's life-support armor.

He's more machine now than man.

FWIW - the "Coincidentally, Kane's cyborg body had a chest plate on his torso that resembled a similar chest plate on Vader's life-support armor." is only a coincidence because this was a comic made a few years ago based on the early text drafts, so, much of the imagery was lifted from the films for consistency. – NKCampbell Jan 29 at 15:06
To elaborate, the actual script describes "a plastic chest stuffed with flashing electric parts": – Stuart P. Bentley Jan 29 at 15:11
