Nerdist: Nickelodeon in the '90s was the home of what's now seen as a renaissance in animation. What was it like to be a part of that?Bartlett: Well, it was the mid-'90s when Hey Arnold came out, and that was a great time for animation. It seemed like they were handing out shows, and there was definitely something in the air; it was incredibly exciting. Nickelodeon kept expandin, and they moved into the studio where they are now in Burbank, and we moved with them after three seasons. Before that we'd been in a more humble setting, but those were the days that everyone loved the most. The crew who worked on the first three seasons of Hey Arnold in this dumpy little place on Vineland--they loved that best. I remember there was this great big room with these little desks, and everyone would catch the same cold each winter. It was totally funky in there but, you know, the journey is the destination.Nerdist: The DVD collection contains some really interesting stuff. Are you excited to share the pilot and the shorts with fans?Bartlett: I am! You know the pilot we shot that on 35mm film, and it was all hand inked animation. You look at that now and it's like a long gone craft. But when I see it it feels great, because it reminds me of how it all started. I've always wanted that version to be available. There are a few different versions, but this the one that I really love. Later, the pilot was used to create "24 Hours to Live" in season one, but I always particularly loved the original pilot. There's something so fun about creating a pilot because you're laying out what you want this entire world to be in eight minutes!Also my super funky 8mm "Arnold Escapes From Church" is on there! That's how actually Arnold started, he was made of clay! I created Arnold in the summer of '88 when I first arrived in L.A. and had worked on Pee Wee, and was doing the Penny Cartoons which were made in the same style of this flat shooter clay. So when I had the chance to work on Arnold I'd learned that technique, and so I animated three stop motion Arnold shorts in my own living room!Will you be grabbing the Hey Arnold Collection?
