Luke lets go of his attachments in ANH, because the Lars are gone. But he's still subject to them with Leia and Han. And when it comes to his father, he's trying to save him. An act of compassion, which is unconditional love. He's doing what Anakin failed to do with Dooku, which was showing him compassion by not killing him. It's about a young boy leaving his world and going off into the unknown, to a great adventure. [...] Star Wars, carries that story on to what happens after you leave and in this particular case, there's a slightly more classic edge to it, in that the fates are there to kind of help Luke realize that, in certain cases you don't have choices. You know, if you choose not to fight evil, eventually it'll just push you up into the wall and you just don't have a choice. It's an inevitability that you can't escape from. And in this particular case, he torn between what he really wants to do; which is go off and join the academy and fight for the Rebellion and have excitement; but then he's also committed to helping his uncle, and to help his uncle build his farm, and his uncle's raised him, he's like his father, and he has his obligations to help put the homestead together. It's very clear from the beginning here, that Luke's fate, even when the aunt and uncle are talking, is not to stay on the farm. A future that's just not in him, his destiny lies in a grander scheme of things. Even they know that. I mean they know it for other reasons, that we don't know about yet." --George Lucas, ANH DVD Commentary. "What Luke is doing in the beginning of Star Wars is finding his own responsibility for his place in the world. He thinks that his responsibility is with his aunt and uncle, and to do his chores. His ultimate responsibility is much larger than that because it deals with a much larger base of humanity—larger more cosmic issues. He is unwilling to look up and see those as something that relate to him. He’s much more looking at the ground and plodding along in his everyday life. So it’s that awakening, first of all, that is the performed by the insider, the magic of Obi-Wan that sends him on the path to self-discovery." --George Lucas, Laserdisc Commentary, Star Wars Trilogy Definitive Collection, 1993. "This scene where Luke deliberately gets himself captured and confronts Vader sort of defines the rest of the movie in terms of the fact that it’s not a chase, or one trying to escape from the other, but it’s an emotional competition between the two of them. And Luke isn’t going to run away from him, he isn’t going to fight him, you know it’s a whole different twist on where you might expect the movie might go. It becomes a direct challenge that Luke has with his father to say “I dare you—I’m not going to run away from this,” which makes it very different in keeping them as villains or in a villain/hero kind of situation. It’s “we’re going to sit down and talk about this.” And again on a lot of levels there are some nice twists in their relationship and how they confront each other. But it’s not just like in The Empire Strikes Back, where it was actually a physical confrontation and a real, you know, cutting arms off and things like that. This is a more emotional, talking kind of confrontation." --George Lucas, ROTJ DVD Commentary, 2004. "Luke is therefore urging Stoic wisdom upon Vader when he tells him to let go of his hate. Unfortunately, hatred has had such a viselike hold on Vader for so long that he tells Luke: "It is too late for me son. The Emperor will show you the true nature of the Force. He is your master now." For servants of the dark side, the true nature of the Force is servitude to evil, enslavement to hate. Like virtues, vices tend to control one's behavior. Vader has used fear and hatred to achieve his ends for so long that now the superior hatred and aggression of the Emperor use him. That is how Vader's mastery of the dark side is at the same time servitude to it." --Star Wars and Philosophy, page 27. "In the end I had a problem in the fight between Luke and his father of why he makes the final turn--Luke makes the final turn to the bad side of the force and tries to kill his father. Richard [Marquand] was trying to block out the fight between Luke and Vader and we got down to that point underneath the throne room there and he said, 'You know the script sort of says that Vader says something that upsets Luke,' or something vague like that. I can't remember exactly what the script said but it was a very vague...spark. And we didn't have that actual moment that we needed where you got the sense that Luke is hiding. He's not going to fight him. He refuses to fight. He'd rather die first and then something turns him around and makes him fight. And I never really came up with a satisfactory answer to that of what he could possibly say to set Luke off. And in the process of evolving the script and evolving the importance of Leia as the sister, it was sitting right there in front of my face and it became obvious that turning her to the dark side would be the thing that would set Luke off again." --George Lucas, ROTJ Annotated Screenplay; 1999. "It will be about how young Anakin Skywalker became evil and then was redeemed by his son. But it's also about the transformation of how his son came to find the call and then ultimately realize what it was. Because Luke works intuitively through most of the original trilogy until he gets to the very end. And it’s only in the last act—when he throws his sword down and says, “I’m not going to fight this”—that he makes a more conscious, rational decision. And he does it at the risk of his life because the Emperor is going to kill him. It’s only that way that he is able to redeem his father. It’s not as apparent in the earlier movies, but when you see the next trilogy, then you see the issue is, How do we get Darth Vader back? How do we get him back to that little boy that he was in the first movie, that good person who loved and was generous and kind? Who had a good heart." --George Lucas, Star Wars Trilogy VHS Boxset 2000. "You learn that Darth Vader isn’t this monster. He’s a pathetic individual who made a pact with the Devil and lost. And he’s trapped. He’s a sad, pathetic character, not a big evil monster. I mean, he’s a monster in that he’s turned to the Dark Side and he’s serving a bad master and he’s into power and he’s lost a lot of his humanity. In that way, he’s a monster, but beneath that, as Luke says in Return of the Jedi, early on, “I know there’s still good in you, I can sense it.” Only through the love of his children and the compassion of his children, who believe in him, even though he’s a monster, does he redeem himself." --George Lucas, “Star Wars: The Last Battle,” Vanity Fair, 2005.
