0:18 - Narrator:  "Jedi trapped on Felucia!  Clones are surrounded by droid forces.  Their only hope is to escape on Republic gunships waiting to land on the embattled surface."  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].
