"It's really fun being involved at the early stages of a film."

When it comes to film work, Dart typically gets in very early in the process, playing with different ideas and helping define the look of a movie. With Big Hero 6, for example, he created a number of sketches showcasing different looks for villains and locations around the fictional city San Frantokyo. He also took multiple stabs at the movie's biggest star, the rotund robot Baymax. "Occasionally the studios get in touch with me to do really early blue-sky development work and play around with ideas," he says. "It's really fun being involved at the early stages of a film because there are no constraints or huge pressure to finish a $100 million film and you can really just explore and imagine stuff."

Whether it's a movie about inflatable robots or a cartoon about super-powered tween girls, Dart maintains a very specific style, one influenced by everything from 1960s advertising to classic spy flicks. That style is perhaps best exemplified by his own personal project, Yuki 7 and the Gadget Girls, about a team of Tokyo super spies.

While he plans to continue Yuki's adventures and keep working in animation, Dart's experience with Cosmos also made him want to explore different kinds of projects in the future.

"I'd love to do something interactive," he says of his future plans, "or more stuff dealing with science and education. Or both!"
