This was curious and I was surprised I missed it when it originally came out. The premise, the camera follows around the "hero" on various philosophical/intellectual ventures and encounters, and while I suspect it was originally filmed it's then run through various photoshop filters to give it a variety of animation styles that reflect the people he's talking with. So - in a way a "cartoon" with highbrow pretensions, but - despite the various animation styles the add to the premise of the film, not detract from it.
Good, not great.
Anyways, such a thing would probably never be done these days, a "director" would merely feed in a pile of prompts to his/her favourite AI and have such a thing generated, far less work...
