^ Nice thinking.

Assuming you want to redub Ackbar with him freaking out, being scared and admitting defeat at the drop of a hat? (Ackbar turned up to 11 basically). What voices could you do that with? One I'd suggest would be Hudson from Aliens...

Lando: "Break off the attack. The shield is still up" etc etc
Flight crew: "Admiral, we have enemy ships in Sector 47"
Ackbar: "Well, that's great. That's just f***in' great, man. Now what the f**k are we supposed to do? We're in some real pretty s**t now, man!"

Combine that with Bill Paxton crying and wetting himself from 'True Lies' and you'd have something
