His (short) biography:
"He attended Shawnee Mission East High School in Prairie Village, Kansas, where he was a writer for the school newspaper the Harbinger. He studied broadcast journalism at the University of Colorado at Boulder. After graduating in '83, he spent four years working on experimental films, which helped him get accepted into the Experimental Animation program study at the California Institute of the Arts."
So we can expect that the third one will be similar to the first two movies...
