We were really fortunate to work [on Pineapple Express] with a studio that was really supportive of these guys. It was before Superbad and Knocked Up had even come out, but everyone just felt really great about them and the energy surrounding Seth [Rogen] and Evan [Goldberg] and Judd [Apatow] - all of these guys - and the idea of getting Franco back into comedy as well.

Every time I improvise I'm aware that I could be ruining what it is that we're doing and we'll just have to do it again.

The good thing about L.A. is that there's always someone more famous 100 yards away from me.

People don't usually wanna kill me for one of my movies until after they've paid 12 bucks for it.

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.

Basically, we [me and Evan Goldberg] started thinking about making a movie that was kind of a weed movie and action movie and had a real kind of friendship story to it, then that would be our favorite movie [Pineapple Express] ever.

I have become a giant fan of the testing process, especially with a comedy. I mean, they tell you what's funny. It's almost tailor-made for people who shoot the way we shoot, trying a million different options and versions of things. Because the audience doesn't laugh at a joke, we put in another joke. If they don't laugh at the next joke, we put in another joke. You just keep doing them and you can get the movie to the point where every joke is funny, if you have enough options in the can.
