I grew up in the '80s where there's a lot of these kind of post-apocalyptic, post-comet, post-whatever it was, so that always captured my imagination a lot as a little kid, that idea of getting access to secret places and being able to roam around where you're not supposed to.
That's always a cool thing to be the voice of what the eyes are seeing. It gives you the role of the Greek chorus and that's always fun to do.
