Rebels - S3E10 - "An Inside Man"

1:36 - Ezra:  "Uh, Ryder, what's the plan?"  In A New Hope, Han asks Luke almost the same thing:  "What's your plan?" [1:11:56].

2:28 - Ryder:  "Eh, wish I could take credit.  Idea came from an old friend of yours."  The phrase "old friend" is also used in Attack of the Clones (where Palpatine suggests "an old friend, like Master Kenobi" to protect Padmé [6:34] and Count Dooku calls Mace Windu "my old Jedi friend" [1:50:24] and just "old friend" [1:56:05]), in Revenge of the Sith (where Obi-Wan says, "Goodbye, old friend" to Anakin as he leaves for Utapau [51:13] and Yoda refers to Qui-Gon as "an old friend" [2:09:56]), in A New Hope (where Leia sarcastically says, "We, uh, ran into some old friends" when Han asks her and Luke where they've been [1:31:33]), in The Empire Strikes Back (where Yoda says that through the Force, Luke will see "Old friends long gone" [1:17:05]), and in Return of the Jedi (where Luke says, "I have a promise to keep to an old friend" [37:37] and Han calls C-3PO "an old friend of mine" [1:11:53]).

7:55 - Ezra (to Kanan):  "Now's our chance to find out what the Empire's up to."  Han uses this same expression in A New Hope when some stormtroopers are distracted by the duel between Obi-Wan and Vader and leave their posts, giving Han and the rest an opportunity to return to the Millennium Falcon:  "Now's our chance; go!" [1:32:02]

13:05 - Stormtrooper (to Kanan and Ezra, in disguise as troopers):  "What's your operating number?"  In A New Hope, an Imperial officer also asks Han this over the comlink [1:15:41].

14:31 - Chopper makes noises that sound like "Trust him!  Trust him!" which is what C-3PO says in The Empire Strikes Back about Lando [1:42:12].

19:04 - Ryder (after Kanan and Ezra emerge from the Imperial walker):  "I don't believe it.  I thought you were in the smaller one."  Luke also says, "I don't, I don't believe it" in The Empire Strikes Back, after Yoda uses the Force to get his X-wing out of the swamp [1:13:10].

21:04 - Thrawn (to Governor Pryce):  "Patience, Governor."  There are a few instances in the movies where characters advise patience, but the closest similarity here is to what Palpatine says to Vader in Return of the Jedi:  "Patience, my friend" [38:57].

Rebels - S3E9 - "The Wynkahthu Job"

0:28 - Hondo (to the Ghost crew):  "I can't tell you how much your welcome warms this old pirate's heart.  You are too gracious."

Zeb:  "I agree."

Yoda makes a similar comment to Padmé near the beginning of Attack of the Clones:  "Seeing you alive brings warm feelings to my heart" [5:33].

Yoda also says, "I agree" in Revenge of the Sith (to Ki-Adi-Mundi's suggestion that it's Obi-Wan who should confront Grievous) [49:09].

1:36 - Azmorigan (about Hera):  "Oh, I remember now, the feisty one."  In Return of the Jedi, EV-9D9 also describes R2-D2 this way:  "You're a feisty little one" [12:04].

3:50 - Hondo (after Sabine asks why he doesn't use his own crew for salvaging):  "Oh, trust me; that is a long, boring story."  Hondo uses it more as an off-handed comment, but Han also says, "Trust me" (to Leia) in The Empire Strikes Back [1:20:06].

6:37 - Sabine (as the salvage operation starts):  "Alright, boys, good luck!"  In The Empire Strikes Back, an unidentified Rebel pilot wishes Luke good luck [36:02] and Luke wishes Lando good luck [2:00:09], and in Return of the Jedi, Han and Lando wish each other good luck [Han to Lando at 50:33 and Lando to Han at 52:21].  Luke also says, "Alright, boys" as the snowspeeders join the battle in The Empire Strikes Back:  "Alright, boys, keep tight now" [26:38].

7:31 - Azmorigan (about a clunk):  "What was that?"

Zeb:  "It's nothing.  It's loose cargo."

Azmorigan:  "I saw something move!  There!"

There's some similarity between this and Luke's discovery of the dianoga in the trash compactor in A New Hope:  "Something just moved past my leg.  Look!  Did you see that!?" [1:19:53]

12:06 - Sabine (after Zeb warns her about the proton bombs):  "I'll be careful."  In the cantina in A New Hope, Luke assures Dr. Evazan that "I'll be careful" [46:46].

14:03 - Hera (to Ezra):  "We're running out of time here!"  Qui-Gon also says this in The Phantom Menace:  "Either way, we're running out of time" [40:07].

14:05 - Ezra:  "Hondo!  Come on, I need your help."  Queen Amidala says the same thing to Jar Jar in The Phantom Menace ("I need your help" [1:37:55]); Obi-Wan to Padmé in Revenge of the Sith ("Padmé, I need your help" [1:38:44]); and Obi-Wan to Luke in A New Hope ("I need your help, Luke.  She [Leia] needs your help." [36:03]).

20:19 - Kanan:  "Punch it, Hera."  Han also says, "Punch it!" to Chewbacca in The Empire Strikes Back [35:35].

Rebels - S3E8 - "Iron Squadron"

4:24 - Jonner:  "Mart's the best pilot in the galaxy."  Obi-Wan gives this credit to Anakin in A New Hope:  "He was the best star pilot in the galaxy" [32:58].

5:33 - Hera (about the Empire):  "They'll be back."  In A New Hope, Obi-Wan also says this, but about the Tusken Raiders:  "The sand people are easily startled, but they'll soon be back and in greater numbers" [31:52].

6:00 - Mart:  "We had everything under control."  Han makes the same claim (to Leia) in A New Hope:  "I had everything under control till you led us down here" [1:19:37].

12:30 - Mart (thinking his detached cargo destroyed the Imperial ship):  "I got 'em!  I got 'em!"  Luke also exclaims this after successfully shooting down one of the Imperial sentry ships in A New Hope:  "Got him!  I got him! [1:35:25]

15:31 - Mart (after the rebels return to rescue him):  "I don't believe it!"  Luke also says, "I don't, I don't believe it" in The Empire Strikes Back, after Yoda uses the Force to get his X-wing out of the swamp [1:13:10].
