I think around that time I met David [Gordon Green] or, well, we all met at Superbad and Judd [Apatow] said, 'I'm thinking about having him direct [ Knocked Up].' Sounded like a good idea.

We made the song a big part of the story [Sausage Party ] itself, in that it's kind of their prayer that they say every morning, because we found that just to have an arbitrary song felt too unrealistic within the reality of our talking food movie.

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

I mean, I love Comic-Con.

We just kind of wanted to play with these iconic moments of action. There's a really small one that always makes me laugh really hard, where there's a big shootout at the end, and the moment my gun runs out of bullets, I turn and there's just another gun sitting there, and I'm, like, oh, nice.

It was a great time. We did hurt ourselves [on Pineapple Express set]. [James] Franco cracked his face open.[Danny ] McBride cracked the back of his head open. I punched Amber[Heard] in the face just to get her in the mood for things. 'Welcome to the set!' But it was a lot of fun. I loved it.

We [with Judd Apatow] started talking about ideas and he said, 'Well, I'm going to do this movie Knocked Up with Seth [Rogen], but after that you guys should do a movie together.' I read it and thought that it was very funny.
