You'd be forgiven for missing the deeper meanings that underlie Adult Swim's hit Rick and Morty, thanks to the animation's incredibly surreal and bizarre sense of humour.

But there's more than meets the eye, as revealed in the musings of co-creator Dan Harmon in a video promoting the forthcoming season of the show.

Harmon reflects on the "heavy theme of creator and createe" in the show. Rick turns out to be "the seam between God and man," but doesn't really give much care to what he creates — even though man has been constantly searching for why they've been created.

While Harmon doesn't subscribe to Rick's belief that nothing matters, if you get through the "terrifying threshold" of accepting it, "every place is the center of the universe," says Harmon, "every moment is the most important moment and everything is the meaning of life."

Yep, there's way more to Rick and Morty than you realised.
