I just thought i'd give a little mention to something I have always found quite amusing,

Throughout 4 out of 6 films we have heard the big hairy one talking and not known exactly what he said. ie,

Chewbacca "Grraggh Rearrgh!"
Han Solo "You said it Chewie"

But then in ANH in the Cantina scene with Han and Greedo, Greedo gets subtitles

Greedo "Awoona poonta Solo" (subtitled) Going somewhere, Solo?

now, seeing as Greedo gets barely 5 minutes of screen time why does he get subtitles when our favourite walking carpet doesn't?
