We don't have any changes in the movie [Pineapple Express] and so picking the right outfit was fairly important. So I wasn't a fan of the Guatemalan pants, but I was convinced that I should wear that. Then the T-shirt is a special creation by David Gordon Green. It's a kitten sitting in a shark's mouth, but he's happy about it.

Sometimes what you lose in the time it takes to let an actor do something that you don't like as a director, you gain in not shutting them down creatively by telling them their idea sucks.

I think people do get better as the movies go on sometimes, and I'm always happy that we're shooting out of order, so it's kind of scattered throughout the movie, and there isn't like a clear build in everyone finding their characters.

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.

I was in high school when Will Ferrell was first on 'Saturday Night Live', and I remember thinking, 'Man, that guy is the funniest guy ever.'

The scene with Danny [McBride] and the cake and all of that [in the Pineapple Express], most of that is improvised, I would say. But you would never know, to me anyway, and that's what is always amazing.

To me, what separates a funny movie from a good movie is something personal.
