"Here's my argument. There's dialogue from frame one. Each of those beeps and those squawks and those whirs mean something and they're trying to convey a specific thing, so I wrote the script with dialogue – wrote it just like a regular script. I would just put the dialogue in brackets. So if he says 'Hey, come over here,' I wrote 'Hey, come over here' and I put it in brackets. Now it was a map for me and anybody else, for Ben Burtt, whoever. When you put in a sound, it's got to convey that. And so it was very conventional how I wrote it."
