12:45 - C-3PO (to R2-D2): "Don't worry about Master Luke; I'm sure he'll be alright." Obi-Wan says the same thing to R2 about Luke in A New Hope: "Oh, don't worry; he'll be alright" [30:17].
18:52 - General Rieekan: "Send Rogues 10 and 11 to Station 38." This is a somewhat disguised occurrence of 1138.
22:12 - Han (to Luke): "You alright?" In A New Hope, Luke asks Obi-Wan, "Are you alright?" [59:16], and Biggs asks Luke [1:46:44].
23:09 - Darth Vader (after General Veers informs him of the Rebels' energy shield): "The Rebels are alerted to our presence." C-3PO uses the same expression in A New Hope when he tells Luke, "I said all systems have been alerted to your presence, sir" [1:17:49].
30:31 - Luke: "Rogue Two, are you alright?" [30:31]
and
31:39 - Han (to Leia): "You alright?"
See above (22:12)
31:49 - C-3PO (to Leia): "Your highness, we must take this last transport; it's our only hope." Leia uses the phrase "only hope" twice in A New Hope: "Help me, Obi-Wan Kenobi; you're my only hope" [35:35] and "You must use the information in this R2 unit to help plan the attack; it's our only hope" [1:38:49].
41:09 - Luke (landing his X-wing on Dagobah): "All the scopes are dead; I can't see a thing." He makes the same comment in A New Hope about his stormtrooper disguise ("I can't see a thing in this helmet!" [1:13:17].
53:46 - Emperor Palpatine (talking to Vader, referring to Luke): "The Force is strong with him." In A New Hope, Vader also says this about Luke, although he doesn't know it's Luke specifically, just a rebel pilot: "The Force is strong with this one" [1:55:41].
59:08 - Leia: "I have a bad feeling about this."
1:00:41 - Han: "This is no cave." This may be intended as an echo of what Obi-Wan says about the Death Star in A New Hope: "That's no moon; it's a space station" [1:04:25].
1:01:18 - Yoda: "A Jedi's strength flows from the Force." Obi-Wan tells Luke something similar in A New Hope: "Remember, a Jedi can feel the Force flowing through him" [1:00:50].
1:06:14 - Vader (addressing the bounty hunters): "You are free to use any methods necessary, but I want them alive, no disintegrations."
Boba Fett: "As you wish."
Vader gives the same instruction to the stormtroopers aboard the Tantive IV in A New Hope ("Bring me the passengers; I want them alive!" [6:08]), and in A New Hope, he says, "As you wish" after Tarkin asks him to release General Motti from his Force choke [38:45].
1:07:09 - C-3PO (to Han): "Sir, we just lost the main rear deflector shield. One more direct hit on the back quarter, and we're done for." He uses the same expression in A New Hope: "You go on, Master Luke. There's no sense in you risking yourself on my account; I'm done for." [32:20].
1:09:12 - Luke (after Yoda implies that he should use the Force to get his X-wing out of the swamp): "Master, moving stones around is one thing; this is totally different!" [1:09:12]. Han's comment to Obi-Wan in A New Hope is somewhat similar: "Look, good against remotes is one thing. Good against the living? That's something else." [1:02:20].
1:10:48 - Yoda (speaking about the Force): "Its energy surrounds us and binds us." Obi-Wan similarly describes the Force in A New Hope: "It's an energy field created by all living things. It surrounds us and penetrates us. It binds the galaxy together." [34:41].
1:14:52 - Leia: "What'd you have in mind for your next move?"
Han: "Well, if they follow standard Imperial procedure, they'll dump their garbage before they go to lightspeed, and then we just float away."
Leia: "With the rest of the garbage."
Han also uses this expression in A New Hope when he says, "Don't worry, Chewie; I think I know what he [Luke] has in mind" [1:12:12]. "The rest of the garbage" might be a reference to Luke's initial reaction to the Millennium Falcon in A New Hope: "What a piece of junk!" [54:37].
1:16:40 - Yoda (to Luke): "Feel the Force flow." An-other similarity to Obi-Wan's "Remember, a Jedi can feel the Force flowing through him" in A New Hope [1:00:50].
1:16:58 - Yoda (to Luke): "Through the Force, things you will see, other places. The future, the past, old friends long gone." Leia also uses the phrase "old friends," albeit sarcastically, in A New Hope; after Han asks her where she and Luke have been, she replies, "We, uh, ran into some old friends," referring to stormtroopers [1:31:33].
1:18:55 - Cloud City official: "Permission granted to land on platform 327."
1:20:04 - Han (to Leia): "Don't worry." "Don't worry" also appears twice in A New Hope: Obi-Wan tells R2-D2, "Oh, don't worry; he'll be alright," referring to Luke [30:17], and Han tells Leia, "Don't worry; she'll hold together," referring to the Millennium Falcon [1:34:57].
1:21:31 - C-3PO (to Lando): "I am C-3PO, human-cyborg relations." He introduces himself (to Luke) the same way in A New Hope: "And I am C-3PO, human-cyborg relations" [20:25].
1:21:41 - Lando (referring to the Millennium Falcon): "You know that ship saved my life quite a few times. She's the fastest hunk of junk in the galaxy." An-other similarity to Luke's "What a piece of junk!" in A New Hope [54:37].
1:44:03 - Vader: "Your destiny lies with me, Skywalker. Obi-Wan knew this to be true." This may not be specifically what he means, but Obi-Wan does say something similar to Luke in A New Hope: "Your destiny lies along a different path from mine" [1:09:53].
1:57:09 - Vader (to Admiral Piett): "Prepare the boarding party, and set your weapons for stun." [1:57:09] In A New Hope, a stormtrooper aboard the Tantive IV says, "Set for stun" [6:24].
