In this scene:
Luke: Vader's on that ship.
Han Solo: Now don't get jittery, Luke. There are a lot of command ships. Keep your distance, though, Chewie, but don't *look* like you're trying to keeping your distance.
[Chewie barks a question]
Han Solo: *I* don't know. Fly casual.
Han's dialogue could be made funny with this addition (from Blade Runner):
Luke: Vader's on that ship.
Han Solo: Now don't get jittery, Luke. There are a lot of command ships. Keep your distance, though, Chewie. Move in.
[Pause with Chewie correcting the course]
Han Solo: Stop.
[Chewie barks a question, slightly confused look of the others]
Han Solo: Pull out, track right.
[Pause with Chewie correcting the course]
Han Solo: Stop.
[Chewie barks a question]
Han Solo: Center and pull back.
[Pause with Chewie correcting the course]
Han Solo: Stop.
[Chewie barks a question, mildly confused look of the others]
Han Solo: Pan right or-and pull back.
[Pause with Chewie correcting the course]
Han Solo: Stop.
[Chewie barks a question, really confused look of the others]
Han Solo: Pull back. Wait a minute. Go right.
[Pause with Chewie correcting the course]
Han Solo: Stop.
[Chewie barks a question, extremely confused look of the others]
Han Solo: Enhance 57 to 19. Track 45 left. Gimme a hard copy right there.[Old style printer spits out a piece of paper][Chewie barks a question]

I don't know where this scene is going. But it struck me as funny. :)
