The Clone Wars - S1E4 - "Destroy Malevolence"

3:44 - Obi-Wan:  "What in blazes are they [Padmé and C-3PO] doing out here?" echoes Obi-Wan's earlier "What in the blazes is he [Anakin] doing there [on Tatooine]?" in Attack of the Clones [1:22:27].

5:42 - C-3PO:  "Oh, we're doomed."  He also says "We're doomed" twice in A New Hope [3:04, 16:02], once in The Empire Strikes Back [1:00:38], and once in Return of the Jedi [10:03].

5:47 - Anakin:  "Somebody has to save her [Padmé's] skin."  Leia has a similar line in A New Hope: "Somebody has to save our skins" [1:18:22], and Anakin uses the same expression in Revenge of the Sith when he says to Obi-Wan, "Alright, but you owe me one, and not for saving your skin for the tenth time" [24:38].

5:52 - Plo Koon: "There he [Anakin] goes again, craving adventure and excitement."  This borrows some words from what Yoda says to Luke in The Empire Strikes Back:  "Adventure.  Heh!  Excitement.  Heh!  A Jedi craves not these things" [56:49].

6:14 - Computer voice: "Welcome to rail jet sub-station nine four."  This is a reference to Docking Bay 94 from A New Hope, first mentioned by Han Solo at 49:18.

9:40 - Obi-Wan:  "Spinning is not flying."

Anakin:  "But it's a good trick."

This is a reference to Anakin's "I'll try spinning; that's a good trick" in The Phantom Menace [1:54:22].

14:25 - General Grievous jumps down behind Obi-Wan Kenobi and says, "Hello, there," the opposite of the situation in Revenge of the Sith [57:27].

15:23 - Grievous:  "I will deal with this Jedi myself."  He says almost the exact same thing in Revenge of the Sith:  "I will deal with this Jedi slime myself" [58:03].  Both times, he's referring to Kenobi.  In Return of the Jedi, Vader says, "I will deal with them myself," referring to the Rebel strike force [56:10].

16:15 -  C-3PO:  "Don't shoot!"  He also says this, also with arms raised, in A New Hope [16:27].

17:49 - Obi-Wan Kenobi uses a crane to swing himself behind Grievous on the train, similar to what Indiana Jones does at the beginning of Indiana Jones and the Last Crusade [7:52].

The Clone Wars - S1E3 - "Shadow of Malevolence"

6:46 - Nala Se: "It is 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]); C-3PO uses it once in The Empire Strikes Back ("Your highness, we must take this last transport; it's our only hope" [31:49]); Obi-Wan uses it once, referring to Luke, in Return of the Jedi ("You were our only hope" [47:24]); and Luke uses it once, referring to Leia, in Return of the Jedi ("If I don't make it back, you're the only hope for the Alliance" [1:19:39]). Sio Bibble also uses it in The Phantom Menace: "Our only hope is for the senate to side with us" [23:48].

7:41 - Anakin: "Cut the chatter, Ahsoka." Red Leader has a similar line in A New Hope: "Cut the chatter, Red Two" [1:45:55].

15:31, 19:30 - As in the previous episode, the Malevolence's ion cannon firing parallels the Death Star's firing in A New Hope, but in the first of these two occurrences, the button-pushing sequence [58:53, 1:56:25] is also included:

17:27 - Plo Koon: "Stay on course" echoes a Gold Squadron pilot's repeated "Stay on target" from the Death Star attack in A New Hope [1:50:43]. 17:30 - Anakin: "All deflectors, double front" echoes Red Leader's "Switch your deflectors on, double front" from the Death Star attack in A New Hope [1:45:47]. 17:55 - Battle droid: "I have a bad feeling about this."

17:58 - Anakin: "Watch those towers, boys." There's also some talk about towers in the attack on the Death Star in A New Hope. At 1:53:48, Wedge says, "My scope shows the tower, but I can't see the exhaust port. Are you sure the computer can hit it?" and then, "What about that tower?" to which Luke replies, "You worry about those fighters; I'll worry about the tower." 18:05 - Clone pilot: "Loosen up" quotes a Gold Squadron pilot [1:50:48] from A New Hope. 21:21 - Plo Koon: "From a certain point of view" quotes Obi-Wan in Return of the Jedi [46:23].

The featurette on the DVD explains that the Y-Wings in this episode (especially their bubble-shaped turrets) were based in part on the Ralph McQuarrie concept art for A New Hope.

The Clone Wars - S1E2 - "Rising Malevolence"

2:38 - Count Dooku: "You may fire when ready."  Twice, Tarkin says the same thing in A New Hope [58:37, 1:56:20].

2:53 & 21:15 - The shot of the Malevolence's ion cannon firing, with droids shielding their eyes, parallels the Death Star's cannon firing in A New Hope [59:02]:

8:59 - Sinker (trying to restore power to the escape pod):  "No, that's not it.  This one goes there; that one goes there."  Han Solo also says, "This one goes there; that one goes there" to Chewbacca while they're fixing the Millennium Falcon in The Empire Strikes Back [29:42].

10:04 - Plo Koon: "Pod 1977, do you copy?" references 1977, the year A New Hope was released.  There's also a resemblance between this and the Imperial officer's "TK-421, do you copy?" in A New Hope [1:08:21], especially since the numbers are pronounced as individual digits ("one nine seven seven" and "four two one"), although that may be coincidental.

20:54 - Ahsoka:  "You forgot; we turned him off" bears some similarity to C-3PO's "'Use the comlink?'  Oh my, I forgot; I turned it off" in A New Hope [1.23.53].

The Clone Wars - S1E1 - "Ambush"

9:37 - Rys: "Where's the General [Yoda]?

Jek:  "I don't know, we got separated."

Luke also says "We got separated" (referring to himself and Leia) in Return of the Jedi [1:02:20].

11:00 - Super Battle Droid:  "Die, Republic dogs!"  When C-3PO's head is on a battle droid's body in Attack of the Clones, he has a similar line:  "Die, Jedi dogs!" [1:53:27]

Star Wars: The Clone Wars

35:25 -  Ahsoka:  "So, this is where the fun begins."  Anakin also says "This is where the fun begins" at the beginning of Revenge of the Sith [3:47], and Han Solo has a similar line in A New Hope:  "Here's where the fun begins" [56:26].

46:02 - It appears earlier, but this is probably the clearest shot of an archway in the monastery:

This is clearly based on a Ralph McQuarrie concept painting from Return of the Jedi of the exterior of Jabba's Palace:

46:40 - Wilhelm scream (clone trooper)

1:03:59 - Anakin:  "Looks like we're gonna have to take this bucket of bolts all the way to Tatooine" references Leia's "This bucket of bolts is never gonna get us past that blockade" in The Empire Strikes Back [35:09].

1:07:19 - Obi-Wan:  "If anyone can fly a bucket of bolts through hyperspace, he [Anakin] can" - same as above.

1:10:54 - Anakin:  "Hang on back there."  Anakin seems to direct this to Ahsoka, but Luke says this to R2-D2 in A New Hope [1:48:52].

1:16:55 - Ziro to an assassin droid:  "What is it, Kronos-327?"  327 is a number that frequently appears in Star Wars.

1:27:58 - Ziro to Padmé:  "I believe you are too dangerous to be kept alive."  In Revenge of the Sith, Palpatine says that Dooku "was too dangerous to be kept alive" [14:38].  Later in the same movie, Mace Windu has a similar line about Palpatine:  "He's too dangerous to be left alive" [1:14:23].

1:28:05 - Ziro:  "I have powerful friends in the senate" echoes what Leia says to Jabba in Return of the Jedi:  "We have powerful friends" [21:02].
