On Norton and the Hulk script, which Penn ultimately received sole credit for (he had been concocting the storyline for 16 years): "Yes, [the fallout] prevented me from collaborating with him [during production]. I don't really know the guy, he has his own process and he chose to do it the way he wanted to do it. That said, I kept in touch with the people making the movie — but he, you know, has his own particular way of working and...it was unusual. I really don't know, I wasn't there, I was off making another movie, so it wasn't a situation where I was banging on the door saying, 'Let me come to the set.' But that was disappointing, I won't deny it. I wasn't happy with him coming to Comic-Con saying that he wrote the script. I can't tell you that made me go back and watch Fight Club."
On The Avengers: "Right now, we're [he and Marvel Entertainment] planning a bigger Avengers movie that will tie all of the movies together, and it's going to bring in a lot of the comic book authors. I am writing, but also, I think you guys [looking at Fergus] are going to be writing with us too, right? [Fergus looks back blankly.] Maybe you don't know that yet, but you are."
