I think every set, we do a little bit better. Everything we do on The Simpsons, any kind of packaging, we try to do as good as the show, we don't just go, "Yeah, here it goes out to everybody."

I went through my archives of old drawings and so did Wes Archer and the other directors, trying to get as much information [as possible], like old drawings and development drawings and so forth.

What's great about this one, is that we have the voice actors adding their commentary to the tapes. That's really great, to hear their perspective, along with writers and directors. I believe this is even richer, with additional materials, easter eggs and so forth.

I haven't seen the final thing put together. The people who did it were very conscientious, and they wanted to cram in as much as they possibly could.
