1:46 - Chancellor Palpatine: "This bomb is our only hope for victory now." 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].
8:47 - Mace Windu: "I have a bad feeling about this."
9:42 - Wilhelm scream (clone trooper)
10:01 - Mace Windu (to clone troopers as Anakin distracts the Zillo Beast): "Now's our chance; let's go!" Han Solo has a similar line in A New Hope, when the lightsaber duel between Darth Vader and Obi-Wan Kenobi distracts the stormtroopers on the Death Star: "Now's our chance; go!" [1:32:02].
