5:03 - Zeb (to Ezra): "So what's the plan, kid?" Han has a similar line in A New Hope when he asks Luke, "What's your plan?" [1:11:56]
7:31 - Stormtrooper (to Zeb): "Hands up!" A stormtrooper also says, "Hands up!" to Han and Leia in Return of the Jedi [1:48:07]. In The Phantom Menace, a battle droid says, "Hands up!" to Jar Jar and Captain Tarpals [2:00:19], and in Revenge of the Sith, one says "Hands up, Jedi!" to Anakin [10:22].
9:37 - Zeb (after fruit splatters the cockpit of the TIE fighter he stole): "Can't see a thing!" Obi-Wan says the same thing in Revenge of the Sith, after the cockpit of his starfighter fogs over ("I can't see a thing" [6:11]), and Luke says the same thing in A New Hope about his stormtrooper disguise ("I can't see a thing in this helmet!" [1:13:17]) and in The Empire Strikes Back while entering Dagobah's atmosphere in his X-wing ("All the scopes are dead; I can't see a thing" [41:09]).
14:59 - Zeb (to Supply Master Lyste, who's suspicious about the stolen TIE fighter): "That's not the TIE you're looking for." This has the same structure as Obi-Wan's line "These aren't the droids you're looking for" in A New Hope [43:40].
15:48 - Mr. Sumar (to Ezra, as he's reaching down to the control panel to release the Imperial prisoners): "It's too dangerous!" In A New Hope, Obi-Wan gives this same warning to Luke as he rushes back to the farm [39:52].
17:58 - Ezra sticks a wrench into the barrel of the turret so that when it fires, the turret explodes, which is basically the same thing that Indiana Jones does with a rock and a turret on a tank in The Last Crusade [1:30:22].
