The Clone Wars - S3E18 - "The Citadel"

4:55 - Fives (about being carbon frozen):  "Are, uh, we sure this thing is safe?  I don't want to end up a wall decoration."  In A New Hope, C-3PO also asks this (to R2 about the escape pod):  "Are you sure this thing is safe?" [7:18].  The "wall decoration" part is a reference to what later happens to Han Solo in Return of the Jedi.

6:52 - Tactical droid K2-B4 (to the Republic's re-programmed battle droid):  "What is your cargo?"  In Return of the Jedi, Admiral Piett asks a similar question:  "Shuttle Tydirium, what is your cargo and destination?" [55:27].  More generally, the whole situation of sneaking into enemy territory in a stolen ship is similar.
