I remember, when I was an up-and-coming comic, how annoyed I would be when the famous guys would show up and just take everyone's spots.
Seth RogenI 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.
