I don't know if this has been mentioned yet (if it has it's probably been by me) but the rouged Wedge jogged my memory.
When Wedge says."One more pass" in the Hoth battle it doesn't sound much like Denis Lawson to these ears, to be honest when I could only listen to The Story Of ESB record to refresh my memory of the film (until it came out on video) I was so convinced that Carrie Fisher delivered the line that I imagined Leia was saying it from the base control centre while monitoring the battle.
Anyone else hear what I mean?
