The twelve-minute film is the result of almost four years of production and tens of thousands of drawings, single-handedly paper animated and photographed by Hertzfeldt.
In the film, the evolution of the human race is traced from prehistory (mankind as blob forms), through today (mankind as teeming crowds of selfish, fighting, or lost individuals), to hundreds of millions of years into the future as our species evolves into countless new forms; all of them still behaving the same way.
Like all of Hertzfeldt's films prior to World of Tomorrow, The Meaning of Life was photographed entirely in-camera, without the use of computers, post-production compositing, or digital tools.
Special features relating to The Meaning of Life include a time-lapse documentary called "Watching Grass Grow" of Hertzfeldt animating the film (apparently over the course of a few years), another documentary about the creation of the special effects narrated by Hertzfeldt, original pencil tests, and dozens of pages devoted to Hertzfeldt's original sketches, storyboards, notes, and deleted ideas from the film.
From a commercial standpoint I guess I’ve made some pretty inscrutable decisions, like following up "Rejected" with a sprawling abstract film about human evolution, but it's really just been whichever ideas won't go away at the time.
