It's been almost 20 years since Matt Groening, creator of The Simpsons, has released a new show. He last did it in 1999 with his sci-fi comedy Futurama. But he says, it hasn't been all work since then.
"I love playing," Groening says. "I love inventing worlds."
As it turns out, Groening has been dreaming up a new universe almost all of that time. His new show Disenchantment is an animated fantasy set in the medieval kingdom of Dreamland.
