7:22 - Sabine: "I don't believe it; this thing has a navi-computer." 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].
8:51 - Sabine (to Ezra): "Don't just stand there; jump!" While in the trash compactor in A New Hope, Leia gives the same command: "Don't just stand there; try and brace it with something!" [1:21:37]
9:38 - Sabine flies the TIE Defender close to the tower at the Imperial landing pad, and the framing and movement match a shot in The Empire Strikes Back where Han flies the Millennium Falcon past the bridge of a Star Destroyer [1:07:39]:
11:49 - Ezra suddenly decreases the speed of the TIE Defender so that the TIE Interceptor pursuing it flies past it. Luke does the same thing with speeder bikes in Return of the Jedi [59:47].
12:24 - Ezra (to Sabine, referring to the last TIE Interceptor): "Don't worry; I'll get him." "Don't worry" also appears in Attack of the Clones (Anakin tells Padmé, "Don't worry; I've given up trying to argue with you" [1:36:02]), Revenge of the Sith (C-3PO tells Padmé, "Don't worry; I'm sure he'll be alright," referring to Anakin [1:24:00], and a clone trooper tells Bail Organa, "Don't worry; the situation is under control [1:24:35]), A New Hope (Obi-Wan tells R2-D2, "Oh, don't worry; he'll be alright," referring to Luke [30:17]; Han tells Chewbacca, "Don't worry, Chewie; I think I know what he [Luke] has in mind" [1:12:12]; and Han tells Leia, "Don't worry; she'll hold together," referring to the Millennium Falcon [1:34:57]), The Empire Strikes Back (C-3PO tells R2, "Don't worry about Master Luke; I'm sure he'll be alright" [12:45], and Han tells Leia, "Don't worry" [1:20:04]), and Return of the Jedi (Lando, referring to Han, tells Nien Nunb, "Don't worry; my friend's down there; he'll have that shield down on time" [1:27:18]).
16:35 - Governor Pryce (to Thrawn): "We've located the crash, Admiral, but there's no sign of the Rebels. I'm initiating a search. They won't escape." An Imperial officer's comment to Vader in A New Hope has the same basic structure: "We count thirty rebel ships, Lord Vader, but they're so small they're evading our turbolasers" [1:46:53]. For "no sign," see above, 0:55.
18:33 - Ezra (about the lothwolf): "I don't believe it." See above, 7:22.
20:55 - Zeb (after Sabine explains that the hyperdrive stolen from the Defender will work in the U-Wing: "Then we can come and go off this rock." Luke uses a similar expression in A New Hope; after C-3PO asks if there's anything he can do to help, he replies, "Not unless you can alter time, speed up the harvest, or teleport me off this rock" [19:58].
