I'm the biggest proponent of test screenings now. There's two ways to face test screenings. For dramas, I don't know if I would rely on them as much, although I still think you need them, because you're making a movie for an audience at the end of the day. But with comedy... You could go through a script or anything I ever worked on, where you go, "This is hilarious," and you put it in front of people and you get nothing. And then the other side of it, is something you're like, "I think this is really stupid," and it gets a giant laugh.
