- “'That is my center. It is what I was born with, eyes that have only seen the wonder in everything! Eyes that see lights in the trees and magic in the air. This wonder is what I put into the world, and what I protect in children. It is what makes me a guardian. It is my center'”
- ―North [src]

- William Joyce was inspired by Sean Connery's portrayal of James Bond for North's character, saying: "There's no way you can be Santa and not have extraordinary technology at your disposal," and "I always saw Sean Connery as Santa Claus. He's got to have a little of James Bond in him."
- North's sleigh is an automated carriage pulled by huge reindeer. The artists designed it to be a cross between a snowmobile and an F-14 jet fighter.
- According to Patrick Hanenberger, North is much closer to the Father Christmas figures around the world than the American version. The German Father Christmas (Knecht Ruprecht) would punish you if you didn't behave. The creators just moved away from the commercial versions and grounded these characters more in mythology.
