Years and years of talking and writing versions of the script [Sausage Party] and looking at various versions of the animations - I mean, it's really a lot of workshopping and trying different things, and using the cast to try different voices and characters. And that's the good thing about animation. Because it takes so long, it allows you to explore in a way that you can't in live-action movies.
