The Clone Wars - S1E15 - "Trespass"

In "Trespass," Chairman Cho and Senator Chuchi constrast in how they perceive and deal with the Talz.  After dead clone troopers are found in the Republic base on Orto Plutonia, Chairman Cho comments that "if it's not the Separatists out there, then it's a malevolent and aggressive enemy nonetheless."  He repeatedly calls the Talz "savages," and when he meets with Thi-Sen, he makes accusatory gestures and declares war.

During this same meeting, Senator Chuchi tries to intercede on behalf of the Talz and even steps between Cho and Thi-Sen.  Her efforts are of no avail here, but after she receives authority from the Speaker of the Assembly to make peace with the Talz, she negotiates with Thi-Sen herself.  Instead of Cho's aggressive posture, hers is a welcoming one.

It's also significant that she takes the slain chairman's hat and places it upon one of the Talz' spears.  Earlier in the episode, this same sort of monument to the Talz' victory is shown with clone helmets and droid heads:

That Chuchi does this with the chairman's hat illustrates that she understands and respects the Talz' culture, unlike Cho who considers them "little more than animals."  At the end of her negotiations, she tells Thi-Sen that she "recognize[s] your sovereignty as a free and equal people."

The title of the episode is ambiguous in a couple ways.  When Obi-Wan tells Chairman Cho about the Talz, Cho is indignant and says, "They're trespassers," but from the Talz' point of view, it's the Pantorans who are trespassers.

As a synonym for transgression, the title could also apply to Chairman Cho's actions, which are deemed "out of order" by the Pantoran Assembly.

The Clone Wars - S1E15 - "Trespass"

1:37 - Obi-Wan (to Chairman Cho):  "With all due respect Chairman, this is for the senate to decide, not us."  In The Phantom Menace, Qui-Gon and Obi-Wan's pilot uses the same expression ("With all due respect, the ambassadors for the Supreme Chancellor wish to board immediately" [2:06]), and Obi-Wan says it in Revenge of the Sith while speaking to Mace Windu about Anakin ("With all due respect, Master, is he not the chosen one?" [40:32]).

4:04 - Anakin (to Obi-Wan):  "Sensors are in place."  Han Solo says something similar in The Empire Strikes Back:  "Sensors are placed" [3:45].

4:08 - Obi-Wan (when the hologram project doesn't work):  "Blast it!"  He also says "Blast!" when Jango Fett ambushes him in Attack of the Clones ("Blast!  This is why I hate flying!" [1:08:22]), and Luke says it twice in A New Hope:  after R2-D2 disappears ("Blast it!" [26:49]) and when a TIE fighter is behind him during the Battle of Yavin ("Blast it, Biggs, where are you?" [1:49:09]).

4:10 - Anakins hits a hologram projector in order to get it working again, just like Han Solo does with the Millennium Falcon in The Empire Strikes Back [35:07].

4:12 - Battle droid (in a hologram recording):  "685 to command.  There're too many of them."  Captain Panaka says something similar in The Phantom Menace (referring to battle droids):  "There are too many of them" [23:25], as does a Jedi youngling in Revenge of the Sith (referring to the clones executing Order 66 at the Jedi temple):  "Master Skywalker, there are too many of them" [1:23:40], and a rebel pilot says basically the same thing in Return of the Jedi (referring to TIE fighters):  "There's too many of them" [1:35:13].

6:36 - Two Talz cross their spears in front of Anakin and Obi-Wan, just as two Gamorrean guards do in front of Luke in Return of the Jedi [22:33]:

6:53 - Obi-Wan (after Anakin asks how he's going to communicate with the Talz):  "Patience.  Maybe they're smarter than we are."  It's unclear whether "Patience" is his answer to Anakin's question or merely his advice, but in The Empire Strikes Back, Yoda and Obi-Wan also counsel Luke with, "Patience!" [Yoda at 54:36 and 55:03; Obi-Wan at 1:24:18], and in Return of the Jedi, the Emperor advises Vader:  "Patience, my friend" [38:57].  It's also part of Obi-Wan's advice to Anakin in Attack of the Clones:  "Patience.  Use the Force.  Think." [21:49].  Also in Attack of the Clones, Dooku, referring to Padmé, tells Gunray, "Patience, Viceroy, patience; she will die" [1:49:27].

8:16 - Anakin (after Rex comments about the weather):  "You don't know the half of it."  He also uses this expression while talking to Kitster in The Phantom Menace:  "That isn't the half of it" [47:59] and then goes on to explain that he's going to be in the podrace.

11:51 - Chairman Cho (after Senator Chuchi offers to represent Pantora):  "Not on your life, Senator.  There will be no diplomacy this time."  There are similarities here to two lines in A New Hope.  After a rebel technician offers Luke a new droid to replace R2, he replies, "Not on your life" [1:43:43], and after Vader gives order to retrieve the escape pod, he says, "There'll be no one to stop us this time" [8:44].

13:59 - Rex (after Chairman Cho orders him to fire on the Talz):  "Sir, with all due respect, we're only here to protect you."  See above, 1:37.

14:11 - Chairman Cho:  "It's a trap!"  Admiral Ackbar is famous for saying this in Return of the Jedi [1:35:03], but Leia says this to Luke (twice!) in The Empire Strikes Back [1:39:50].

19:03 - Obi-Wan (urging Senator Chuchi to negotiate with the Talz):  "Senator, now is the time."  The situation is quite different, but while speaking to Tion Medon in Revenge of the Sith, he says something similar:  "If you have warriors, now is the time" [55:19].

21:14 - Anakin (to Senator Chuchi):  "Yes, most impressive."  Vader gives a similar compliment to Luke in The Empire Strikes Back:  "Impressive, most impressive" [1:44:30].

21:38 - Senator Chuchi (after Obi-Wan tells her to make the peace last and set an example):  "I will; I promise you."  In The Phantom Menace, Obi-Wan tells Anakin, "You will be a Jedi; I promise" [2:07:43], and in Revenge of the Sith, Padmé tells Anakin, "I'm not gonna die in childbirth, Ani; I promise you," and he replies, "No, I promise you" [53:46].  Later, Anakin also tells her, "Things will be different; I promise" [1:29:13].

The clone troopers' cold weather gear is based on a Ralph McQuarrie concept painting of snowtroopers for The Empire Strikes Back.  Captain Rex's helmet even includes the same symbol on the side:
