World of Tomorrow. World of Tomorrow is an animated sci-fi short film series from filmmaker Don Hertzfeldt. In the broadest possible terms, it follows a young girl named Emily who, later in life, is cloned many times and has her clones visit her younger self through time travel. The clones tell Emily stories of the future while she reflects on the present and things veer toward the mind-blowingly profound while also being funny, scary, heartfelt, and everything in between. Hertzfeldt not only writes and directs the shorts, but animates them, edits them and more, all by himself. Each film is a staggering achievement, and he’s just getting started.
