Darths And Droids 2: Should've Gone to Naboo

[The Glyphstone]

Or possibly role-playing the 'imprisioned' part on occasion.

That'll be hard to do without screencaps...we see Leia exactly three times from the Tantive IV to Luke's rescue of her; when she meets Tarkin, when they torture her, and when they blow up Alderaan. Not a whole lot of material to stretch out over 2/3 of the movie.
